Dynamic and Thermal Study of the Three-Dimensional Flow in a Flat Plate Solar Collector with Transversal Baffles

Three-dimensional numerical analysis of the thermo-aerodynamic characteristics of air- plane solar collectors and improving thermal efficiency through baffle design: a comparative CFD study

“…He studied a solar collector with two passes in comparison with the model of Ben Slama Romdhane using the ANSYS calculation code to perform a simulation to provide results in a short timeframe and at minimal cost. M. A. Amraoui et al [9] introduced baffles on the fluid vein of the airplane solar collector using 3D simulation. They observed an increase in the length of the sensor trajectory and the speed of the air and the heat transfer.…”

“…They introduced baffles in the solar collector to increase the fluid flow path and observed that airspeed and heat transfer increased (M.A. Amraoui et al [20]). However, the size of the dead zones was considerable.…”

Three-Dimensional Numerical Simulation of a Flat Plate Solar Collector with Double Paths

“…There are several works built to provide solutions that improve the performance of the flat air solar collector. Amraoui and Aliane [1] have done a digital study of solar collector created by Ben Slama Romdhane. because of the solutions is not feasible because of the limitations and the very expensive cost they passed from experimental work to the work of simulation by the code of calculation ANSYS, therefore the CFD gives very clear results with very complex situation, they did a numerical study of a planar solar air collector with turbulence promoters "transverse baffles", they started with the validation between the experimental results and the numerical results.…”

“…Amraoui and Aliane [4] have made a study of a solar flat plate collector by three-dimensional simulation (CFD) which reduces time and costs, the objective of this work is to compare the results theoretically by the results experimentally to validate the results obtained by the simulation and afterwards they made a study of an air flow in a solar air sensor equipped with transverse and longitudinal baffles to improve heat transfer, they gave results on the distribution of temperature, speed and turbulence on the air stream of the solar collector.…”

Turbulent Flow Around Obstacles: Simulation and Study with Variable Roughness

“…Moreover, Merahi et al [20] carried out a study that contributed to understanding the three-dimensional stationary and incompressible flow through a cascade of blades using a numerical simulation based on the k-ε model; they found out that the pressure losses due to the change in the angle of incidence are the main causes of the decline in the performance of turbomachines. Similarly, Amraoui and Aliane [21,22] investigated the fluid flow and heat transfer inside a solar flat plate collector using Computational Fluid Dynamics (CFD) by introducing suitable baffles inside the solar air collectors in order to decrease the pressure losses and increase the temperature. As regards Dogan et al [12], they examined the characteristics of a flow around a surfacemounted cube for Re = 3700 using the Computational Fluid Dynamics (CFD), while considering three different types of turbulence models; the results obtained were then compared with the experimental ones.…”
