Air Behavior Inside Duct of Air Solar Collector with Three Models of Baffles
Abstract
The objective of this work is to study numerically the effect of the geometry of the baffles on the heat exchange in a solar air collector. Three models of collector were used in this study, fitted with simple baffles and perforated baffles. Fluid dynamics calculation (CFD) tool has been used to simulate the geometries of the solar collectors. Its three models involving air intake, are modeled by the FLUENT6.3 software and the grids were created with the Gambit software. The shape of the perforations is in the forms strips perforated in the baffles. The numerical resolution uses the finite volume method and the turbulence modeling K-Epsilon. The results have been validated by previous work and the simulation results are in terms of the evolution of the axial velocity and temperature distribution for the three models.
