A Prediction Method for Fin Efficiency Calculations During Film Condensation on Horizontal Integral Fin Tubes with R32/R134a Mixtures

摘要

This paper presents a general analytical model to predict the heat transfer coefficient for film condensation on horizontal integral fin tubes for R32/R134a mixtures in 20/80%, 30/70%, 40/60% compositions by mass, and a parametric study of fin efficiency using tubes from Wieland Co. Our algorithm has been developed by use of theoretical aspects and techniques encountered in thermal problems. The heat transfer performance is investigated as a function of fin/tube geometry and refrigerant property.
