In this article, we present an investigative study on the often-overlooked partial wake phenomenon in previous studies concerning wind farm configurations. A partial wake occurs when a portion of the actuator disk of a downstream wind turbine is affected by the wake of another upstream turbine. This phenomenon occurs in addition to the full wake, where the entire upstream turbine is affected by the wake of the frontal turbine, also leading to a decrease in wind speed and consequently a reduction in power production. The proposed study is based on measuring the power generated by the area swept by the wake of an array of turbines in a wind farm. To accomplish this, we integrate the linear wake model of Jensen, the specifications of the ENERCON E2 wind turbine, and the wind farm data into Matlab-developed software (version 18) to perform the calculations. In a concrete application, this proposed method is validated by reproducing the previous works that neglected the partial wake in wind farm configurations. The simulation results obtained are analyzed, compared, and discussed under similar operational conditions.

The aim of this study is to investigate mixed convection flow of nanofluid around a three-dimensional (3D) finned angular sector of heat sink by means of numerical simulations. The finite-volume method is used to solve the governing equations of mass, momentum, and energy conservation. The Brownian motion of the nanoparticles in the base fluid is explicitly taken into account in the thermal conductivity model (Patel model). A parametric study is carried out to examine the effects of several key parameters on the rate of heat transfer; the angular sector apex angle, the volume fraction of suspended nanoparticles (0 ≤ φ ≤ 0.09), the Richardson number (Ri = Gr/Re2), and the size of the nanoparticles diameter (5, 20, 60, and 100 nm). It is shown that for a fixed low Richardson number Ri, the rate of heat transfer increases with the volume fraction of the nanoparticles, as forced convection mechanism is dominated. The heat-transfer enhancement is obtained for the nanofluid water/TiO2 rather than the water/Cu at higher nanoparticles volume concentration and highest Richardson number. Moreover, the Maxwell thermal conductivity model resulted in a maximum enhancement in the case of nanofluid water/TiO2 than that of water/Cu, whereas the nanofluid water/ Cu gives better heat-transfer enhancement at small particles than that of water/TiO2. It is observed too that the nanoparticles' diameter does not have a significant effect on the temperature field.

This paper presents a numerical investigation of natural convection heat transfer in an annular enclosure filled with nanofluid. The inner cylinder is fitted with longitudinal fins and subjected to volumetric heat generation while the outer cylinder is kept adiabatic. The governing equations of mass, momentum and energy equations for both the fluid and the solid are solved by the finite volume method, using the commercially available CFD software Fluent 6.3.26. The effect of the size of the nanoparticles on the rate of heat transfer is carried out and investigated. The study has been conducted considering two nanofluids of based water with Al2O3 and TiO2 nanoparticles for a solid volume fraction (0≤ ϕ ≤ 0.09) and nanoparticles diameter of (5nm,20nm, and 80nm) at Rayleigh number Ra=12000. Results have shown that adding nanoparticles in the base fluid have produced an increase of the rate of heat transfer. The nanofluid water/Al2O3 gives better heat transfer enhancement at small particles diameter than the nanofluid Water/TiO2

In this paper, we propose a numerical study of the natural convective heat transfer flow in a three dimensional cylindrical and divergent annular duct. The inner cylinder subjected to a volumetric heat generation is fitted with longitudinal fins. The governing equations of mass, momentum and energy equation for both the fluid and the solid are solved by the finite volume method, using the commercially available CFD software Fluent. The effect of the inclination angle ϕ of the divergent and the fin parameters on the profiles and the contour fields of temperature and velocity as well as the average Nusselt number ratio were investigated for ϕ=0°,15°,23° and 45°and several fins, N=1,2,3 and 4. The Simulations were carried out in the range of Rayleigh numbers (Ra = 100 to Ra=6.3x104). The results reveal that the increasing of the inclination angle of the divergent and the number of fins enhance the heat transfer.

This work presents the numerical results of the mixed convective heat transfer of a three-dimensional flow around a radial heat sink composed of horizontal circular base fitted with rectangular fins. The governing equations of mass, momentum and energy equation are solved by the finite volume method using the commercially available CFD software Fluent 6.3.26. The circular base of the heat sink is subjected to uniform heat generation, the flow enters through the sides of the heat sink around the fins then the heat is transmitted from the base to the fins afterward the fluid. In this study two fluids are utilized, in the first case, the air for the following Reynolds numbers Re=600,900,1200 and a Grashof number Gr=3.7x106, in the second case a water-based nanofluid for which two types of nanoparticles (Cu and Al2O3) are carried out for Re=25 and a Richardson number Ri=2.7(Ri=Gr/Re2). The effect of the number of the fins of the heat sink as well as the type and the volume fraction of nanoparticles of the nanofluid were investigated. Results have been presented for N=15 and N=20 fins. The effect of the nanoparticles concentrations and the number of fins on the temperature in the heat sink and the Nusselt number has been studied.
