摘要
采用形状因子对应态原理,由纯流体的蒸汽压和饱和汽液相密度方程得到的保形参数,由此推算其它区域内的P-V-T性质、第二virial系数、焓、熵、热容和混合物的汽液平衡等热力学性质。
With the conformal parameters evaluated from the equations of the vapor pressure and molar volumes of pure fluid at saturation state,the shape factor CSP is used to predict the thermodynamic properties of P V T,second virial coefficient,enthalpy,entropy,heat capacity and vapor liquid equilibrium for both pure fluids and fluid mixtures.Satisfactory results are obtained.
