摘要
对超压泄放过程进行了热力学分析 ,推导了闪蒸两相流泄放等熵指数的表达式 ,对比分析了闪蒸和非闪蒸两相流泄放等熵指数的差别 ,给出了纯气体或蒸气、闪蒸和非闪蒸两相流泄放过程泄放量计算的统一表达式。
A thermodynamic analysis of the overpressure relief is conducted. An expression is derived for the isentropic exponent for flashing flow. A comparison is made between the isentropic exponents for flashing flow and non flashing flow. A generalized relief capacity correlation is given for gas, vapor, mixed two phase of vapor and liquid for flashing flow and non flashing flow.
