Effect of Protein Blends main structural parameters of shutter baffle heat exchanger with a triangle tube layout in the shell side on heat transfer and flow resistance performance is studied in the article.A periodic whole cross-sectional computation model is built for the heat exchanger in the numerical study.The effects of structural parameters are analyzed, including assembly mode of shutter baffles, shutter baffle pitch, strip inclination BEECH angles, and strip widths.The correctness and accuracy of numerical simulation method are confirmed with a laser Doppler velocimeter experiment.

Based on the research results, correlations for heat transfer coefficient and pressure drop in shell side are presented.Using the field synergy principle, the heat transfer enhancement mechanisms of segmental baffle heat exchanger and shutter baffle heat exchanger in shell side are analyzed.
