高温湿空气热物理性质计算方程

Equation for Calculating Thermophysical Properties of High Temperature Moist Air

由于高温状态下温空气不能作为理想气体处理。为此,文章依据二元组分混合气体性质,根据实际气体压缩因子和维利状态方程,建立了由空气温度、压力和相对湿度表达的高温湿空气热物理性质的计算方程,并为方便工程计算,将这些方程整理成为相应的修正系数乘以纯干空气的热物理系数。

According to virial equation of state for real gas. The equations on the basis of properties of dual gas mixture for calculating the density, specific heat capacity at constant pressure, viscosity and thermal conductivity of high temperature moist air expressed in terms of air temperature, pressure and relative hunidity are derived. For the convenience of engineering calculation, these properties are arranged with the dry air termophysical properties multiplied by appropriate correction factors.
