The Generalized Correlation for Friction Factor in Crisscross Flow Channels of Plate Heat Exchangers

摘要

The paper concerns with analysis of the influence of corrugation form of PHE plates onrnhydraulic resistance in the formed channels. The data for models of the main corrugatedrnfield of the inter-plate channel considered. It enables to exclude the influence ofrnentrance and exit distribution zones. The specific type of generalizing formula is used,rnwhich correlates the data in a wider range of Reynolds numbers, compare tornconventional ones. The equation for hydraulic performance of inter-plate channels withrnsinusoidal and triangular corrugations shapes is obtained, which generalizesrnexperimental data of different authors available in literature. It accounts for therninfluence of the corrugation inclination angle to the plate vertical axis and corrugationsrnpitch to height ratio.
