摘要
Abstract
In this paper,the gas-liquid conversion of CFD calculation model in capillary network is established by adding the quality source terms and energy source terms of two-phase flow in user-defined functions.Condensation performance of R22 in smooth tubes of small diameter is researched.The condensation process of R22 is calculated on different gaseous phase inlet flow velocity by CFD model.The pressure drop,the condensation coefficient and the velocity correlation curve are obtained.It provides a theory basis for the radiation end design of small diameter capillary net,and a guidance for the choosing of refriger-ant flow rate.关键词
