The Heat and Momentum Transfers Relation in Channels of Plate Heat Exchangers

摘要

The link between heat transfer intensity and hydraulic resistance of PHE channels isrndetermined with the use of modified Reynolds analogy of heat and momentum transfer.rnThe formula to estimate the share in total hydraulic resistance of pressure loss due tornfriction is proposed. The resulting model enables to calculate film heat transferrncoefficients in PHE channels on a data of hydraulic resistance of the main heat transferrnfield. The calculations are compared with the available in literature experimental resultsrnon heat transfer in channels with cross corrugated walls. The good agreement confirmsrnthe assumptions made on deriving equation and existence in PHE channels of thernanalogy between heat and momentum transfer in proposed form.
