Intensification of heat transfer in liquid heat exchangers with dimple-pin finning

Abstract

The authors consider the possibility of intensification of heat transfer in fluid heat exchangers with cavity-pin finning by changing the shape of the cavities. It is shown that the transition from circular to elliptic cavities leads not only to a significant intensification of heat transfer but also reduces the size and weight of the heat exchanger.
