A Computerized System for Calculating Physical Properties of Matter

物性计算系统是各种动力 化工流程仿真平台不可缺少的基础支撑,其正确性、普适性和鲁棒性将直接影响平台表现。本文旨在讨论如何建立一个可以处理任意相态、任意种类纯物质混合物、高效而稳定的物性计算系统,快速计算混合物的各种热力学函数值。实现过程独立于特定平台及特定系统。

Physical property computing systems(PPCS) constitute the fundamental supporting part of various kinds of simulation platforms of power generation-chemical engineering processes, where their exactness, practicability and robustness have a direct bearing on the simulation platforms' behavior. How to establish a highly efficient and stable PPCS is being discussed in the paper, which would be able to handle any mixture of pure matter in any state and promptly calculate their various thermal-dynamic functional values. The calculation process would be independent of the specific platform or system. Figs 3, table 1 and refs 10.
