摘    要:以Lee-Kesler熵差图表为基础,采用正交筛选法建立了实际流体等温熵差计算的三参数关联式,选取多种化合物的5147个熵差文献值对该式进行了考核,并与LK,PR,SRK,BWRS及ZRK等状态方程的计算值作了对照检验。结果表明,本文提出的关联式方法简单,预测气、液相熵差的精度都较高。


NEW CORRELATIONS OF FLUID DEPARTURE FUNCTION (Ⅱ) ISOTHERMAL ENTROPY DEPARTURE
Abstract:3-parameter correlations to estimate the fluid isothermal entropy departure function are developed by means of Orthogonal Sieving method, based on Lee-Kesler's tabular entropy data. The calculated values are checked against 5147 literature data points and compared with those calculated by EOS—— LK,PR, SRK, BWRS and ZRK. The results show that the correlation is much convenient and accurate in calculating entropy departure of gas or liquid.
