摘要：
In this study, we have designed and developed a ribbed type solar air heater on the basis of theoretical studies. After the successful development of solar air heater, we have carried out some experimental result like outlet temperature and velocity of air. On the basis of experimental study, we have found that the temperature improvement is about 30-40 degrees C at free convection. The impact of temperature on mass flow rate, heat transfer rate and mass flow rate on pressure drop, friction factor, Reynolds number and Nusselt number is investigated. A significant enhancement is found in Thermal efficiency due to the ribs.
