Abstract

Numerical analysis of thermo-hydraulic performance parameter (ƞ) of a solar air heater having sine wave shape obstacles is carried out and compared with a flat plate air heater. The second-order upwind scheme is used for discretization of the fluid domain and governing equations are solved by the Semi-Implicit Method for Pressure-Linked Equations (SIMPLE) algorithm. Shear Stress Transport (SST) k–ω turbulence model is used for modeling turbulence. The numerical analysis encompasses Reynolds number (Re) ranging from 4000 to 16,000, and angle of attack (α) ranging from 0° to 45°, while the relative roughness transverse pitch (p/e) is kept 10. Numerical analysis is performed by using computational software ANSYS Fluent 15.0. The thermo-hydraulic performance parameter (ƞ) based on Nusselt number (Nu) and the friction factor attained maximum value at (p/e) of 10 and α of 30°.
