摘　　要：分析了实际气体在节流减压过程可用能的损失,以实际气体熵和焓的微分方程为依据,通过等压和等温过程积分,推导出实际气体节流减压过程的可用能损失公式并进行仿真,结果表明:可用能损失随出口温度增加而增多.The available energy loss in throttle pressure relief process is studied.Based on differential equations of entropy and enthalpy of the actual gas and the integration of constant pressure and isothermal processes,the available energy loss formula is derived.Simulation shows that the energy loss increases as the outlet temperature increases.

关 键 词：减压阀 节流减压 实际气体 可用能损失
