Transient Numerical Simulation of a Large-Sized Cement-Mill Fan for Performance Prediction
In many engineering applications, particle-laden flows are a necessary part of the conveying process, but in other situations, they could have unintended consequences that must be avoided. As a part of the exhausting process, the induced cement-mill fan (FN-280) installed in a cement plant operates under critical conditions with the presence of high content of cement particles. Over time the dragged solid particles erode the rotating and stationary parts of the fan causing their damage. If one decides on a numerical ap-proach to predict regions most prone to erosion and track the solid particle's trajectory within the fan domain by assuming a one-way coupling regime between the continuous and dis-crete solid phases, a deep insight into the flows physics within the centrifugal fan is required. With this aim, a three-dimensional numerical approach for the hole unsteady flow in a large-sized industrial centrifugal fan has been carried out in this paper. A fully resolved sliding mesh approach was employed to take into account the unsteady interaction between the impeller and the discharge volute. Based on the characteristic performance curves, the numerical results of the unsteady simulation at four operating conditions are val-idated with the experimental data. The comparisons reveal that the results of the unsteady simulation are in an accepta-ble level of agreement with the experiment, demonstrating the validity of the modelling approach adopted in this study.

RETRO DESIGN OF IMPELLER BLADE OF THE INDUCED DRAFT FAN (FN-280) USING A COORDINATE MEASURING MACHINE (CMM)
Centrifugal fans are widely encountered in engineering practices, they are essential in the cement production process. The three dimensional, complex and turbulent flow in a centrifugal fan makes the prediction of the performance of the centrifugal fan and the examination of the flow field very difficult. Computational techniques have made a great progress, because of time and cost that may be involved in experimental analysis of the flow, computational fluid dynamics (CFD) is intensively used in many industrial purposes. Nevertheless, the agreement between the numerical results and real data is a subject of many researches, because the numerical result is very sensitive to the numerical method being used, the boundary conditions applied, mesh generation and turbulence model selection. To consider the interaction between the main three parts of the fan namely the inlet, impeller, and scroll, it is necessary to carry out a three-dimensional Numerical simulation of the flow field for the whole centrifugal fan. The impeller is the important part of the centrifugal fan and the aerodynamic design of the impeller blades affects the flow passage, thus improving the aerodynamic design of the blades results in improvements of fan performance and reduction of flow separation. The selection of turbulence model depends on the flow separation that can occur, particularly in the blade passage, thus in order to get a good numerical investigation of the performance of the fan and predict the internal flow field in the impeller, a Coordinate measuring machine (CMM) machine is used as a reverse engineering tool to extract the original impeller blade design of the induced Draft fan (FN-280) by using Geomatics software for point cloud processing.

3D CFD MODEL FOR THE ANALYSIS OF THE FLOW FIELD THROUGH A HORIZONTAL AXIS WIND TURBINE (HAWT)
With the world’s growing demand for energy, renewable energy production has become important in providing alternative sources of energy and in reducing the greenhouse effect. This study investigates the aerodynamics and performance of the WG/EV100 micro–Horizontal Axis Wind Turbine (HAWT) using Computational Fluid Dynamics (CFD). The complexity of VAWT aerodynamics, which is inherently unsteady and three-dimensional, makes high-fidelity flow models extremely demanding in terms of computational cost, limiting the analysis to mainly 2D Computational Fluid-Dynamics (CFD) approaches. This article explains how to perform a full 3D unsteady CFD simulation of HAWT. All main parts of the WG/EV100 HAWT were designed in SOLIDWORKS. Only the blade design was reverse engineered due to the unavailability of the CAD model and the complexity of its geometric characteristics. The impeller blade is scanned using a Coordi-nate Measuring Machine (CMM), and the obtained 3D scan data are exported from the PC-DMIS software to GEOMAGIC design X to obtain a CAD model of the blade.

flexion of sandwich beams by the finite element method
Multi-layered composite materials (Sandwiches) occupy a wide range of applications in many industrial fields such as aerospace, aviation, vehicle, shipbuilding, civil engineering and even for wind turbine impeller blade manufacturing for power generation. They emerged as a strong competitor with traditional materials as a consequence of the need for different combination of mechanical proprieties for many production facilities. Nevertheless, the common defects of multilayer composite materials during manufacturing and finishing processes are the main cause for their gradual damage. The progressive application of these materials has driven many researchers to study the mechanical proprieties and their behavior under various forms of damage. application of finite element methods method (FEM) to structural analysis has progressed steadily and has proven to be an effective tool over the last decades. Regarding this fact, in the present work, a numerical modeling of the sandwich beam with nine layers as face, sheets is carried out by simulating three points bending test. the CAD model of the Sandwich was performed by using the available commercial software ANSYS Composite PrepPost (ACP) 2022 and the FEM analysis was conducted by means of ANSYS static structural 2022 to determine the mechanical properties of a multilayer composite material subjected to flexion experiments.

Thermal analysis of photovoltaic panels using numerical method
Traditional sources of energy (fossil fuels) still fulfill the world’s energy demand as it plays an important role in the rapid progress of industrial development. Nevertheless, owing to the increasing price of fossil fuels and their impact on the environment, the demand for sustainable and environmentally friendly energy sources rises to meet the high energy demand. Many promising renewable energy technologies have emerged, including photovoltaic cell (PV) technology, which is widely used in power generation plant. There are various types of photovoltaic cell technology, including amorphous silicon, monocrystalline silicon, and polycrystalline silicon. The production loss on solar system is regularly attributed to the photovoltaic panel. One of the most issue the photovoltaic cell system face during operation is that a small percentage of solar radiation is converted into electricity, While the rest is converted into heat. The operating temperature of the photovoltaic panels is considered one of the diverse factors that affect the performance of the panels, therefore. This research paper aims to perform a numerical simulation to model the temperature distribution of a photovoltaic (PV) panel in a real-world operating condition. the CAD model of the photovoltaic (PV) panel was created employing the commercial software SOLIDWORKS (2022), and the thermal analysis was conducted using ANSYS Steady-State Thermal.
