R513A在不同微肋管内的冷凝换热和压降特性
Condensation heat transfer and pressure drop characteristics of R513A in different micro-fin tubes
摘要
Abstract
A kind of smooth tube and two kinds of micro-fin tubes were studied to analyze the effects of tube type,mass velocity,condensation temperature,and other parameters on heat transfer coefficients and pressure drop.Heat transfer correlations were validated.The experimental results indicate that compared with smooth tube,micro-fin tubes exhibit higher heat transfer coefficients and greater pressure drops.The heat transfer coefficient and pressure drop of micro-fin tubes increase with the increase of mass velocity and with the decrease of condensation temperature.Both micro-fin tubes demonstrate superior overall performance at low mass velocities.The Shah correlation and Fujii correlation show mean absolute errors of 5.41%and 5.65%for the smooth tube,respectively.The Ubudiyah correlation shows the mean absolute error of 10.76%for the micro-fin tubes.关键词
