Abstract: 

The present work deals with the experimental investigation of flow and heat transfer studies in a counter flow double pass solar air heater. To achieve the higher heat transfer from the absorber plate to the flowing air stream with an intention to increase the amount of the collected energy, and hence to improve the instantaneous efficiency, a unique double pass solar collector concept has been used in the present study. To investigate the effects of Reynolds number, tilt angle, β=20º and mass flow rate on the performance parameters of the Solar Air Heater, a detailed experimental analysis has been made. Apart from achieving higher collector performance, the present study is also important from the fundamental point of view.
