低温管路水击现象仿真研究

Simulation research of the water hammer in cryogenic pipelines

为研究低温管路水击现象,利用SINDA/FLUINT软件对典型低温管路关阀过程进行仿真计算,得出了关阀速度、管长、管径、贮罐压力与水击压力之间的关系,结果表明关阀速度、管长、贮罐压力对水击压力有显著影响,管径对水击压力无显著影响。

SINDA/FLUINT was used to simulate the valve- closing process in typical cryogenic pipelines to research water hammer. The research obtained the relationships among valve -closing speed, pipe length, pipe diameter, tank pressure and water hammer pressure. It shows that valve - closing speed, pipe length and tank pressure have a significant effect on water hammer pressure, but pipe diameter has no significant effect on water hammer pressure.
