摘要
对高温换热介质———导热姆 (Dowtherm)的热力学性质进行理论研究 ,并给出一套热力学性质数据包括饱和气、液密度、蒸汽压、气化热和热容等 ,为高温换热设备工程设计计算提供参考。
TONG Jing shan 1,KE Hong ying 2 (1 Department of Chemical Engineering,Tsinghua University,Beijing 100084;2 Chinese Society of Engineering Thermopohysics,Beijing 100080) The thermodynamic properties of high temperature heat transfer agent(Dowtherm)were investigated based on molecular thermodynamic analyzing method.This paper provides also a set of available thermophysical property data,including saturated densities,vapor pressure,vaporization heat and heat capacity etc,for engineering calculations.The common advantage of these estimating methods is simple and convenient in use,they need only a few known parameters,that is critical properties ( p c, T c, Z c)and centric factor(ω).
