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

Flat air solar collectors are used for heat transfer between the absorber and fluid, to improve this there several methods. Among these methods, exchange surface lengthening creation of turbulence. In work is done give a comparison two types collectors, so we have made an improvement Ben Slama Romdhane's collector by creating flow passages increase transfer. We 3D simulation flat with transverse baffles which causes turbulence increases surface; use ANSYS calculation code make gives results brief time minimal cost.
