Abstract
To enhance the efficiency of the solar air heater collector, this study installed an inclined prismatic fin and built an absorption area utilizing v-corrugated absorber plates. The CFD program was used in this investigation to simulate the properties of fluid flow and heat transport numerically. A fluent software with double precision and the Shear Stress Transport k-ω- (SST-kω-) turbulence viscous model was used to run three-dimensional simulations to study the impact of installing fins with different fin thicknesses of 3 mm, 4 mm, and 5 mm, and fin angles of attack of 22.5o, 45o, and 67.5o, respectively. A constant heat flux of 430 watts/m2 and an input velocity of 6.5 m/s are used to test the fin numerically. Simulation results show the optimum fin configuration was achieved by 3 mm in thickness and 67.5o angle of attack, with 9.621 K temperature difference from inlet to outlet collector, the pressure drop is 229.625 Pa, Effectiveness Ratio (ER) is 0.2499, and the highest Q-useful energy is 96.147watt.
