Název v původním jazyce

The effect of plate size and corrugation pattern on plate heat exchanger performance in specific conditions of steam-air mixture condensation

Popis výsledku v původním jazyce

The results of mathematical modelling and experimental study of plate heat exchangers (PHEs) in steam-air mixture condensation are presented. The mathematical model is validated by test data for PHE in the industry and for five experimental samples with corrugation angles, 30 degrees, 45 degrees, and 60 degrees and corrugation heights 5, 7.5 and 10 mm. With no limited pressure drop in PHE, its heat transfer area can be decreased up to 4 times with the plate's corrugations angle of 60 degrees. When pressure drop on the side of condensing stream is limited, at a small mass fraction of air, PHE with corrugated plates' heat transfer area can be smaller than in PHE assembled from flat plates about 1.5 times +/- 11% at channels of different corrugations geometries. For commercially produced plateand-frame PHE, the pressure losses at channel entrance and distribution zones should be accounted. For plates with a corrugations angle of 60 degrees, their share in total pressure drop can be from 7% up to 39.3%, while at a corrugations angle of 30 degrees, up to 59%. The final choice of corrugation angle and height for plates designed for specific duty can be made by solving a future optimisation problem with a developed mathematical model.
