摘　　要：This paper explains the experimental performance evaluation of a Corrugated Type Solar Air Heater(CTSAH)for understanding its performance in a humid tropical climatic condition in Puducherry,India.This helps in understanding its effectiveness in using it for drying application of products like seafood,etc.Experiments were conducted at different mass flow rates and their effect on the heat gain,efficiency,friction factor heat transfer,etc.,was analyzed.Experiments were carried out at different mass flow rates,i.e.,M1=0.06 kg/s,M2=0.14 kg/s,M3=0.17 kg/s,M4=0.25 kg/s,M5=0.3 kg/s,and were conducted from 11:00 h to 14:00 h.The air inlet&air temperature is found to be at an average of 40°C whereas the incident solar radiation is at an average of 795 W/m2.Experimental results show that the optimum performance of the CTSAH is in the mass flow rate range of 0.14–0.25(kg/s).Also,the calculated useful heat produced,convective heat transfer coefficients,effective efficiency,optical efficiency provides knowledge on the potential use of the air heater.
