Solar drying of tomatoes in Hodna region
Solar drying, as a method of extracting water from a solid by evaporation, has been adopted to dry and therefore preserve as much as possible agricultural crops and medicinal plants. The Hodna region, a city in the interior of Algeria, with a semi-arid climate, is known for its high consumption of tomatoes, raw and dried. The use of solar drying of this commodity seems necessary given the climate of the Hodna region and its solar input throughout the year. This work consisted of manufacturing an indirect solar dryer by locally available means, which are not expensive. Then the solar dryer produced, includes a solar collector, a drying chamber, a connection pipe, and some accessories such as thermometers and a thermo-hygrometer. Solar irradiation, ambient temperature, wind speed, collector inlet and outlet temperatures, absorber temperature and drying chamber temperature as well as relative humidity are measured and represented. These results obtained are in good agreement with the theoretical results and the weight of dried tomatoes is reduced by one seventh. Keywords—Solar, drying, tomatoes.

Effets de la poussière sur les performances thermiques d’un capteur solaire plan à air
Les capteurs solaires plans à air et à effet de serre, jouent un rôle primordial aussi bien dans le chauffage des habitations ou le séchage des produits agricoles. Comme la présence de la poussière sur les capteurs solaires est inévitable, les effets de la poussière sur les performances thermiques d’un capteur solaire plan à air, sont étudiés par voie expérimentale. Les écarts de températures d’entrée et sortie du capteur sont mesurées et représentées avec et sans de la poussière. Trois capteurs solaires plans sont fabriqués par des matériaux localement disponibles et qui sont issus de la récupération. L’un de ces capteurs est bien nettoyé pour servir par la suite comme cas de référence, les deux autres ont reçu deux grammes et quatre grammes de poussière. Les résultats obtenus ont démontré que la poussière a des effets négatifs sur les performances thermiques des capteurs solaires, en effet, plus la poussière est importante, plus les écarts de températures sont proches les uns des autres et par conséquent la quantité de chaleur reçue par le fluide caloporteur devient moindre. Donc, la poussière que l’air ambiant porte et déposé sur les vitres des capteurs nécessite un entretien systématique pour que le capteur solaire plan à air garde ses performances thermiques. Mots clés : Capteur solaire, Poussière.

Effets de la poussière sur le comportement thermique d’un capteur solaire plan à air
Aujourd’hui les capteurs solaires plans et à effet de serre jouent un rôle important dans le chauffage des habitations et dans le séchage des produits agricoles. Les capteurs solaires à air sont des machines transforment l’énergie solaire en provenance du soleil en énergie thermique. Comme ces machines sont installées en plein air, le dépôt de la poussière est inévitable. Des études théoriques et expérimentales ont été faites pour mettre en évidence le phénomène de poussière. La présente étude consiste à construire un capteur solaire plan à air et par suite déposer de la poussière. Le capteur construit a été construit par des matériaux récupérés et recyclés. Les résultats obtenus ont permis d’étudier les conditions climatologiques de l’expérience et par conséquent mesurer et tracer les profils de l’irradiation solaire, la vitesse du vent, la température ambiante et enfin l’humidité relative.

Effects of thermophysical parameters on solar distilled water production
Water, a vital material for human life, is becoming scarce day by day, due to the overconsumption of this material in all areas of life and especially in the industrial sector. Previous theoretical and experimental studies have shown that solar water production is a good alternative. Despite the efficiency of solar water production, the quantity produced remains limited, so that the use of improving production remains a major challenge. Among the methods used, the use of the incorporation of nanoparticles in the base fluid to improve the production of distilled water. In this context, this study attempts to increase the production of distilled water by solar means by playing on the thermophysical parameters of the nanofluid (nanoparticles + base fluid), by quantifying the ratios of CuO nanofluid particles. The study showed that the correlations of the thermophysical parameters of water are not able to reflect the results obtained experimentally. The effects of nanofluids on the daily production of distilled water, the overall efficiency and internal efficiency and the temperature of the absorber are determined and represented. The formulas used for the calculation of the thermophysical parameters did not give the expected results in comparison with the experimental ones.

Effects of Temperature and Solar Radiation on Photovoltaic Modules Performances Installed in Oued Keberit Power Plant, Algeria
This study presents the measured data of the "Oued Keberit" PV plant over a period of four months (January to April 2022) after nearly 6 years of outdoor exposure to the climate of Souk Ahras, eastern Algeria, in order to evaluate the performance of the solar PV system. This evaluation includes the calculation of PV system performance variables such as module performance, final performance and performance of the module references, system losses, photovoltaic friendly efficiency, system efficiency, performance ratio and capacity factor based on measured data, allowing comparison of actual PV system performance and reference values determined by manifacturers. The results showed that the four-month average values of the parameters Eac, Yr, Yf, PR, , CF are 1.06375125MWh, 4.08h, 4.25h, 1.06, 16.40%, 60.28% respectively. Also, the high efficiency of the photovoltaic system was obtained during winter, due to the low temperature and the sufficient amount of solar radiation. However, the photovoltaic system generates a lot of energy during summer, although there is less output than during the winter season. This is because summer has maximum values for sunshine duration and solar radiation.

Optimization of control parameters of a compressiblelaminar boundary layer
The control by suction of a compressible laminar boundary layer of a stationary, viscous and subsonic flow, around a two-dimensional NACA 0012 profile, has been studied numerically. The physical problem is governed by nonlinear partial differential equations called Prandtl equations. The numerical solution is based on the Cranck-Nicolson scheme, the Thomas algorithm and the Keller method. The results obtained made it possible to determine optimal values for the extent, angle and flow rate of suction. With the optimal values of the suction control parameters, we were able to achieve a laminarity gain that reached 10%. Keywords: Parametres, Controle, suction

Effet of blowingcontrol on the point of separation of a compressible laminar boundary layer around a two-dimensinal profile
The energy consumption of aircraft, compressors, turbines and others is closely linked to the forces that oppose the proper functioning of these machines. Thus, reducing drag (drag force) by control procedures has been a problem for decades. Among the means of controlling or reducing the effects of the resistance forces, mention is made of maintaining the laminar regime to the detriment of the turbulent regime which consumes more energy. The present numerical study of a boundary layer type stationary compressible laminar flow around a two-dimensional profile with and without puff control. The modeling of the physical problem based on the equations of conservation, continuity, dynamics and energy, simply called the Prandtl equations. Like these partial and nonlinear differential equations, their resolution can only be obtained numerically. The solution procedure is based on the Newton method, the Cranck-Nicolson scheme and the Thomas algorithm. The results obtained allowed the optimization of the blowing control parameters such as the extent, the angle and the blowing flow rate, which also allowed the improvement of the laminar regime by 10% and consequently a consequent reduction of energy consumption. Keywords: Control, Blow; Extented; Boundary layer.

Experimental Study of an Inclined Wick Solar Still Operating in Drop by Drop System Under The Climatic Conditions of Hodna's Region, Algeria
Solar distillation is a very economical process for the fresh water production, especially in arid and semi-arid areas where solar energy is abundant. Several types of solar stills have been designed and manufactured for a purpose to increase their performances. This work aims to study experimentally under outdoor conditions of Hodna’s region, two types of solar still, the first is an inclined solar still with different wick thicknesses (thick, medium and thin) operating in drop by drop system of feed water and the other is conventional. Four clear days of the April months have been chosen to experiment the solar stills performances. The results showed that the solar stills performances are notably influenced by design and operating conditions, as revealed by the daily production and efficiency values of the inclined solar still with thin wick which achieved 4.14 liter/m2.day and 46.66%, with an improvement of about 23.21% and 12.56 % respectively, compared to those of the conventional solar still, which reached 3.36 l/m2 and 34.1% respectively. In addition, the economic analysis illustrates that the low cost of one liter of distilled water and the quicker payback period at the same time are for the inclined solar still with a thin wick of about 0.011$/l and 77 days respectively.

Numerical Study of a Basin Type Solar Still with a Double Glass Cover Under Winter Conditions
A numerical analysis of a basin-type solar still with a double glass cover is done under winter circumstances of solar radiation, ambient temperature, and wind speed. Equations defining thermal balances of different components of traditional and double glass cover solar stills are used to describe the physical issue, which is then solved using the Gauss-Seidel numerical technique. The effects of solar radiation, ambient temperature, and wind speed on the daily production, internal efficiency, and overall performance of solar stills are calculated and illustrated. The findings demonstrate that a solar still with a double-glass cover is more productive and efficient than a solar still with a single glass cover.

EFFETS DU REFROIDISSEMENT PARIETAL SUR LE POINT DE SEPARATION D’UNE COUCHE LIMITE LAMINAIRE COMPRESSIBLE
Le contrôle du point de séparation d’une couche limite laminaire compressible par refroidissement pariétal d’un profil d'aile bidimensionnel dans un écoulement stationnaire, visqueux et subsonique est étudié par voie numérique. Le contrôle par refroidissement pariétal a permis de réduire l’épaisseur de la couche limite et d’étendre la zone laminaire d'environ 10%, permettant ainsi la réduction du frottement pariétal et de là produisant une amélioration conséquente des performances aérodynamiques du profil. Mots clés : Contrôle, refroidissement pariétal, point de séparation, couche limite, laminaire, compressible.

COMPRESSIBILITY EFFECTS ON DISTRIBUTIONS OF PRESSURE AND LIFT COEFFICIENTS
Reduce energy consumption of airplanes, or enhance the aerodynamic performance of compressors and turbines by reducing drag, or increasing lift is a major challenge for many institutions specializing in aerodynamics [1, 2]. One way to achievethis, isconsidered the study of compressible potential flow compared to incompressible potential flow [3], Outside the boundary layer, to study the effects of compressibility and the control parameters. And the pressure coefficient and lift distributions around the NACA 0012 profile, NACA 0015 and NACA 0018 were studied and presented in terms of the Mach number, angle of attack and the relative thickness of the profiles. Keywords : compressibilité, coefficient de pression, coefficient de portance

Semi Analytical Study of a Flat Surface Uniformly Accessible in a Permanent Laminar Flow and a Newtonian Fluid
The authors calculate the profile of a rectangular pipe by imposing the density J(x) of the limit flow of diffusion on a reactive surface placed at the centre of the pipe to fulfill the law px xJJ 0)( = (where 0J is an independent factor of the coordinates and p a numerical constant ). x is the co-ordinate in the flow direction. They consider the flow in the pipe of an Ostwald fluid and link the allowed values for p to the behavior index n of the fluid. The particular case of a surface uniformly accessible (p = 0) of a Newtonian fluid (n = 1) is studied by integrating the equation for mass transfer by approaching the transversal component of the speed V * by polynomials in the interval [ ]wy,0 . As the Sherwood number should be independent of the x co-ordinate (accessibility hypothesis), they come to show, using the error function properties, that the average Sherwood number on the central material plan is written as Sher = a . Pem 1/3 where a is a constant which is independent of the Reynolds number. The calculations treat the mass transfer case and they are transposable to the heat transfer by substituting the Sherwood number by that of Nusselt, and the mass fraction of the conveyed substance by temperature. Keywords: Fluid mechanics, mass transfer, uniformly accessible surface central material plan is written as Sher = a . Pem 1/3 where a is a constant which is independent of the Reynolds number.

Control of the Laminar Boundary Layer around a Profile by Suction
A laminar and two-dimensional incompressible boundary layer around a profile and its control using suction is studied numerically. The study is based on the Prandtl boundary layer model. Using the method of finite differences and the Crank-Nicolson scheme. The study concerns the flat plate case and the 0012 NACA profile. The velocity distribution, the boundary layer thickness and the friction coefficient distribution are determined and presented with and without control. The application of the control technique, has demonstrated its positive effect on the detachment point and the friction coefficient. The control procedure is applied for different porosity lengths, speeds and angles of suction Keywords: boundary layer, laminar, two-dimensional, incompressible, profile control, suction, and friction coefficient
