适用于计算机程序计算的湿空气计算方法

本文旨在提出一种适用于计算机程序计算的湿空气状态参数计算方法。本文通过采用最小二乘法对饱和水蒸气压力试验数据进行分段二次多项式拟合,由此得出一个分段计算函数,并提出建立在此分段函数基础上的湿空气状态参数计算方法。通过与已有经验公式及实验数据对比表明此方法具有较高的计算精度。经过实践证明,此方法适用于编写需要进行湿空气计算的相关计算机程序。

A Method for Computer Program to Calculate State Parameter of Moist Air

The purpose of this paper is to propose a calculation method for computer program to calculate moist air state parameters. A piecewise function is obtained by quadratic polynomial fitting the experimental data of saturation vapor pressure with the least square method, and a method for calculating state parameter of moist air based on this piecewise function is proposed. The high accuracy of this method is certified by comparing the result with the existing empirical formulas and experimental data. It has been testified that this method can be applied to write the relevant computer programs which need to calculate the state parameters of moist air by practice.
