EFFECT OF ABSORBER SURFACE SHAPE ON THE FORCED THERMAL CONVECTION OF SOLAR AIR COLLECTORS

Author

Abstract
In this research a study effect of absorber surface shape for solar air collector
(Flat V-Corrugated, Sinusoidal Wave-Corrugated, Rectangular-Corrugated)(1 1 0.1m) titled to the horizontal by an angle(30o) on forced heat transfer and skin friction coefficient by Fluent Numerical Program at constant solar heat flax (530W/m2) with Reynold’s number (5000≤Re≤8000).
The government equation (mass, momentum and energy) are using Finite Volume by (Fluent 6.3) software for considering steady state, two dimensional and turbulent flow. The results show that the different between inlet and outlet air temperature is(13.65oC) and best heat transfer coefficient enhancement is(63%) for (V-Corrugated plate) compared with the flat plate at (Re=8000), Also the results show that the maximum skin friction coefficient is occured at (V-Corrugated) Cf=0.22 at (Re=8000).
