摘要:
燃气的流速与流量在壅塞流动状态下将受到一定影响。以气体动力学为基础,采用BWRS状态方程,建立稳态仿真模型,对等截面管道壅塞流动状态下的最大流量进行了计算。以CNG罐车管长10m的加气与卸气高压胶管为例,求出了其在不同条件下可通过的最大流量,讨论了燃气流速、压力、马赫数、温度等参数的沿程变化规律。
Abstract:
Flow velocity and flowrate of gas will be certainly affected under the condition of choked flow. Based on gas dynamics,steady state simulation model is established by means of BWRS equation of state. Calculation is made on maximum flowrate of choked flow under the condition of constant section pipe. Taking the 10 m-long gas loading and unloading high pressure sebific duct of CNG tanker as an example,the maximum flowrate flowing through at different conditions is solved,and variation laws of parameters such as gas flow rate,pressure,Mach number and temperature along pipeline are discussed.
