Experimental investigation on thermo-hydraulic performance of triangular cross-corrugated flow passages, International Communications in Heat and Mass Transfer, 122, 105160. https://doi.org/10.1016/j.icheatmasstransfer.2021.105160.https://hdl.handle.net/10388/14880Heat 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.enCorrugated passagesHeat exchangersPressure dropFriction factorNusselt numberArticlehttps://doi.org/10.1016/j.icheatmasstransfer.2021.105160
