安全阀开启高度对其排放能力影响的数值模拟

The numerical simulation of discharge capacity of PRV at different lift

提出了安全阀三维可压缩流场计算模型的建立方法,并利用这一数值模拟的方法,研究了开启高度对安全阀排放能力的影响规律,通过对流场直观的分析,给出了对其影响机理的认识。

This paper put forward the method of three-dimensional compressible flow calculation model of pressure relief valve,and studied how the lift influence the discharge capability of the pressure relief valve by using this numerical simulation method,and through a visual and detailed analysis of the flow,acquired a thorough understanding of the mechanism of the influence.
