Abstract
Heat exchangers made of corrugated flow passages generally have better thermo-hydraulic
performance compared to parallel flow passages. The corrugation angle (), corrugation pattern,
and the ratio of depth to pitch (hch/Pch) are critical geometrical parameters influencing the heat
transfer and pressure drop in corrugated flow passages. This paper experimentally investigates
heat transfer and pressure drop characteristics of triangular-shaped cross-corrugated flow passages for the range of 25°<<75° and 0.13<hch/Pch<0.36. Experiments are performed using
representative compact heat exchangers in a small-scale test facility. This study also reports the
effects of plate geometry on heat transfer and pressure drop and provides correlations for the
average Nusselt number and friction factor. A detailed comparison of test data with relevant
literature is also presented. Results of this study will be useful to manufactures and designers for developing high-performance heat exchangers.
