Experimental study on effect of inter-wall tube cylinder on heat/mass transfer characteristics of corrugated plate fin-and-tube exchanger configuration

Plate fin-and-tube heat exchangers are widely used in air-conditioning equipment. In order to enhance the air side heat transfer, corrugated fins are often used instead of plane fins. The corrugated fins are, in essence, plates that have been fabricated with a periodic waviness in the streamwise direction. Although a number of research works have been performed to investigate the heat transfer and pressure drop performances of plate fin-and-tube heat exchangers, only a limited number of publications are related to the corrugated plate fin-and-tube heat exchangers.
