摘要
经统计力学椎证,建立新的流体状态方程。确定了新方程的气体形式,实现了气体参数普遍化。结果表明,该气体方程用于PVT性质计算,压力偏差小于3%、密度偏差小于5%的置信水平在91%以上;用于纯气体逸度系数计算,偏差小于5%的置信水平在97%以上。
In this paper a new equation of state for fluids has been obtained by the derivation based on the theory of statistical mechanics. A gas form of the new equation has been presented and the gas parameters have been generalized. When the gas equations are used to calculate PVT properties of gases, the confident levels at which the deviations are less than 3% for pressure and less than 5% for dencity are greater than 91%. When they are used to calculate fugacity coefficients of pure gases, the confident levels at which the deviations are less than 5% are greater than 97%.
