不同波纹比例新型板式换热器的传热、阻力特性及(火用)分析
Heat transfer and resistance characteristics and exergy analysis of new-type plate heat exchanges with different corrugation ratios
摘要
Abstract
Four kinds of corrugated plate heat exchangers (PHE) were simulated applying three-dimensional CFD software-ANSYS-CFX. Three-flows plate heat exchanger whose computational domain is 1-1 process, includes import and export segment and reflux section. The results from numerical simulations show that Nusselt number of the working fluid in new-type PHE with Φ=60°,compared with the chevron-type one, is increased by 15% , the flow resistance is decreased by 10% , and the performance evaluation criteria is increased by 20%. The plate with corrugation ratio of 3 : 1 is better than any other type.关键词
