An Empirical Study of a Pin Fin Heat Exchanger in Laminar and Turbulent Flow

Abstract

This study concentrates on the empirical characterization of a staggered array pin fin compact heat exchanger placed in a modular, rectangular wind tunnel. A full analysis of the heat transfer and pressure drop behavior was conducted on various pin-fin shapes, sizes, and configurations. The study was based on airflow over a range of low Reynolds numbers in the laminar and low turbulent flow, as well as higher turbulent flow regimes. The empirical data gathered can be used to corroborate and develop better numerical models to characterize the performance of such compact heat exchangers.
