摘要
为了探讨天然气混合气体粘度和雷诺数的计算方法,依据具体工程实例,给出了已知组分和平均流量天然气混合气体动力粘度、运动粘度和雷诺数的计算实例。并对粘度计算误差和雷诺数计算中体积流量的取值方法可行性进行了分析。同时给出了用C++Builder程序实现的人机界面。程序运行表明,这套方法的计算结果满足该系统对天然气流动状态及计量误差分析的要求。
To study a calculating method for natural mix gas viscosity value and Reynolds number, a calculating example to known composition and average flow natural mix gas dynamic viscosity, kinematical viscosity and Reynolds number is provided. And the calculating error of viscosity and feasibility that take volume flow data method for Reynolds number calculating are analized. The man-machine interface realized by C ＋ ＋ Builder program is also given. The result of program operation shows the calculating result meets the requirements of natural gas flow state and measurement error analyze to the system.
