【摘要】 <正> 一、引言 流体热力性质的重要性及其计算的复杂性促使人们对热力性质计算进行研究与探讨。利用通用计算图进行计算是工程计算中常用的方法.然而以往文献在提出各自的通用计算图时(如以T_r,为参数、以p_r为横坐标的偏差函数图、逸度系数及压缩因子图等)都没有从各热力性质间的内在联系上构思、编绘,当需要同时进行几种热力性质的计算时就要用到几张有关的图,计算很不方便。更多还原

【Abstract】 Based on the Lee-Kesler three parameter equation, a three-parameter diagram of determining the thermodynamic properties of fluids were designed for simplifing the computation procedure. This technique permits quite a simple way to obtain the deviation enthalpy, deviation free enthalpy, diviation entropy, deviation internal energy, deviation free energy, fugacity coefficient, density, enthalpy, difference, entropy difference, internal energy difference, enthalpy-exergy and internal energy exergy and their components of thermo-exergy and mech-exergy for nonpolar and weakly polar working fluids and their mixtures.更多还原
