摘要
本文提出一种用于计算高压天然气粘度的数学模型。使用本模型时,先求解天然气密度,再计算天然气粘度,在广泛的温度(37.8～171℃)、压力(0.69～55MPa)范围内,用本模型进行考核计算;模型计算值与实测值可很好地相符。
A mathematical model for calculating the viscosity of high pressure gas is presented in this article.While this model is used, the gas density is calculated first and then its viscosity. In the large ranges of temperature(37.8～171℃)and pressure(0.69～55MPa), using this model to make an examinational calculation, the value calculated is well coresponded with that measured in practice.
