气嘴流动特性及温降计算方法

A Study on the Nozzle Flow Characteristic and the Temperature Drop Calculation Method

    摘要
  • 摘要: 讨论了气嘴节流和管道内绝热节流流动的特点, 对两者进行了比较和分析, 并计算得到了天然气绝热节流工程中温度随压力的变化曲线, 得出在高压下天然气节流同样会产生温升效应。给出了气嘴节流温度计算方法, 并分析了节流后温降的原因。

     

    Abstract: Based on the discussion of nozzle and pipelines choke characteristic, the differences are compared and analyzed. The relationships between the temperature and pressure for natural gas are plotted. The method used to calculate the temperature drop in nozzle is proposed.
