In this research paper, a Solar Air Heater (SAH) with triangular fins has been experimentally and numerically analyzed validated. The novelty of work is the selection type fins, not only enhance turbulence heat transfer to air but have lower material consumption as compared rectangular fins. ANSYS 2022, Computational Fluid Dynamics (CFD) software used for numerical study, post processor simulation results velocity, pressure, temperature field at pressure Roserland boundary conditions determined by using k-ε standard model steady state. coefficient friction factor are two important parameters that determining rate drop over surface (SAH). For enhancing minimizing drop, optimized geometry must be required. consideration fact, in research, Heat Coefficient (HTC) Friction (FF) Response Surface Methodology (RSM). input variables namely Reynolds Number (Re) pitch height ratio (p/L) selected maximizing performance SAH. velocity contour shows reached maximum between narrow gap due conservation mass. So, flowing increasing optimum values response Nusselt Number, Thermal Performance Factor obtained 176.5064, 0.0260, 1.8903 16928.2180 P/L 1.3430.
