An Experimental Study of a Pin-Fin Heat Exchanger

Abstract

A detailed experimental study has been carried out on the heat transfer and pressure drop characteristics of a compact heat exchanger with pin fins, A modular wind- tunnel with a rectangular cross-section duct-flow area was constructed that would accommodate the heat exchanger test section with varying pin designs. The flow in the tunnel was achieved through a suction-type blower, and a leading entrance length section was added to achieve predictable flow conditions into the heat exchanger test section. The rig was comprehensively instrumented to provide all desired thermal and flow data. The results from this study provide useful empirical data to validate ongoing numerical studies of such heat exchanger designs.
