摘　　要：针对高温高压条件下蓄能器快速泄压过程进行动态模拟。结果表明:初始液位与压力的增加导致蓄能器最终温度、压力上升;研究条件下,散热损失对过程影响较小;HNE模型预测值与文献试验值误差较小更适于本体系的计算。The energy accumulator pressure relief process at high temperature and pressure was dynamically simulated. The dynamic simulation result shows that increasing initial temperature and pressure can lead to the rise of accumulator＇ s final temperature and pressure; and under the research condition, the heat loss influ- ences the pressure relief process less ; the small error between HNE model＇ s predictive value and experimental result demonstrates that HNE model answers to this system.
