Experimental investigation on effect of fin shape on the thermal-hydraulic performance of compact fin-and- tube heat exchangers

The aim of this paper is to investigate the effect of fin shapes on the performance of compact finned flat tube heat exchangers. Three types of fin shapes namely plain, wavy, and rectangular grooved fins attached to three by three arrays of flat tube banks were considered. Moreover, the tubes were d...
