Abstract
In this work, the numerical analysis has been carried out for discrete multi V-shaped and staggered rib roughness surface absorber plate. The thermohydraulic performance has been carried out by considering Fluid outlet temperature, heat flux, glass surface temperature, turbulence kinetic energy and thermal efficiency. The variables consider for the study are fluid inlet temperature and velocities. The highest thermal efficiency that can be achieved by the solar air heater is about 30%.
