EXPERIMENTAL INVESTIGATION ON A SOLAR AIR HEATER WITH AND WITHOUT OBSTACLE

Abstract

 In this paper convection form of heat transfer is used to convert cold air to hot air. Forced convection is preferred for this experimental analysis; obstacles are also used to analyze the temperature level of air with the help of Air Heating Solar Device (AHSD). Semi Annular fins are used as obstacles for this experimental verification. The outlet temperature and pressure drop of SAH were determined by changing the fin densities with the help of software tool FLUENT. The analysis result shows that the outlet temperature is more and pressure drop was less in the case of SAH with obstacles when compared to the SAH without obstacles.
