✦ Synopsis

In this paper, the results of year round thermal performance of collector of semi-cylindrical solar tunnel dryers (STD) has been presented. The calculations have been made under natural circulation and forced circulation mode. The day-long average of solar irradiance, ambient temperature, rise in the inlet air temperature, natural circulation volume flow rates, and collector efficiency have been calculated for each month of the year. The effect of collector length, cover radius, collector inclination with horizontal have been made for rise in inlet air temperature, volume flow rate and for the efficiency. All calculations have been made for Delhi climate.
