摘　　要：确定了空气与轻烃燃气的混合比,类比混合气体动力黏度计算法则,采用平方根规律法和REFPROP软件计算出不同混合比下混空轻烃燃气的动力黏度,得到混空轻烃燃气动力黏度较准确的计算方法。结果表明,平方根规律法和REFPROP软件计算得到的混空轻烃燃气动力黏度值相差不大,可以为混空轻烃燃气管网设计和水力计算提供数据参考。The existing standards and codes do not provide the calculation method of dynamic viscosity of air-light hydrocarbon mixing gas.The mixing ratio of air-light hydrocarbon mixing gas is determined,the dynamic viscosity of air-light hydrocarbon mixing gas under different mixing ratio is calculated by square root method and REFPROP software by analogy with calculation rule of dynamic viscosity of mixed gas,and a more accurate calculation method of dynamic viscosity of air-light hydrocarbon mixing gas is obtained.The results show that the dynamic viscosity values calculated by the square root rule method and REFPROP software differ little,which can provide data reference for the design of the air-light hydrocarbon mixing gas pipe network and hydraulic calculation.
