  Effective efficiency of return flow solar air heater

  By Vikram Singh, Abhishek Kumar Goel

  Abstract: In this paper, the effective efficiency of a return flow solar collector with artificial roughness in the form of V shaped ribs is presented as a function of parameters pertaining to roughness like angle of attack (α), and relative roughness height (e/D) and other relevant operating parameters. Analytical methods were used & governing energy balance equations are used to evaluate results. Plots on these aspects have been presented and discussed …
