混合物物态方程的体积相加模型和热力学自洽条件

VOLUME ADDING MODEL AND THERMODYNAMIC SELF CONSISTENCY FOR EQUATION OF STATE OF MIXTURES

介绍了一个表列数据相加模型，用体积压强迭代法编程计算混合物物态方程。在各组分材料物态方程满足热力学自洽条件的前提下，证明了混合物物态方程也满足热力学自洽条件。最后给出两个算例（空气和ＸｅＤ２体系）。

In this article we present a volume adding model to calculate EOS of mixture numerically using tabulated EOS data for its constituents with volume pressure iterative method.Meanwhile,it is proved that if each of the constituent EOS satisfies the thermodynamic self consistency,their mixture EOS will do also.Finally EOS of atmosphere and of Xe D 2 are calculated as the examples.
