Heat Transfer Enhancement in Solar Air Heater: A Review

Alok Bharti ^[2] | Prof. P. B. Ingle

Abstract: Investigators have shown that by providing the obstruction in the flow of air through the duct enhances the heat transfer of solar air heater. This enhancement is accompanied by considerable rise in pumping power. In view of the fact the investigator needs to carefully examine the method of providing obstruction in the flow. In this paper some methods of providing obstruction in the flow have been formulated on the basis of heat transfer enhancement and thermo hydraulic performance. The objective of this paper is to review the various methods used to enhance the heat transfer rate with little penalty of friction. Correlations developed by various researchers with the help of experimental results are discussed in this paper. These correlations are used to predict the thermo hydraulic performance of solar air heaters.
