摘　　要：基于压缩气体的容器动力学特性,提出高压储气罐小孔泄漏参数的计算方法。以氢气储罐和一氧化碳储罐为例,分别计算储罐壁面小孔泄漏和储罐连接短管泄漏情况下的泄漏质量流率以及储气罐内温度、压力等参数随时间的变化趋势。计算结果表明,泄漏口孔径和泄漏初始压力对泄漏质量流率的影响显著,泄漏口上游管长对泄漏质量流率的影响不明显。Based on vessel dynamics of compressed gas,the calculation method for the parameters of outflow through small holes in high-pressure gas tank is presented.Taking a hydrogen storage tank outflow through a hole in the tank wall and a carbon monoxide storage tank through hole in pipe as the case,the trends of the mass flow rate and the temperature,pressure and other parameters inside the tank are computed.The results show that mass flow rate is influenced by the hole diameter and the initial pressure of vessel,while the influence of the pipe length is not so strong as expected.
