| 摘 要： | 为了克服现有天然气脱水技术的不足,基于气体动力学和传热传质学理论提出了一种新型的天然气超音速分离管装置.介绍了其基本结构和分离机理,对装置内部流动进行了合理假设,建立了几何模型,并利用张量形式的时均方程组对其内部的稳态可压缩湍流流动进行了求解,结果发现在轴向-400 mm至-200 mm之间发生了激波现象,导致气流速度急剧下降,压力急剧上升,温度急剧上升.计算结果与之前的实验结果基本一致,为分离管几何结构优化提供了理论基础.

| Abstract: | In order to overcome the deficiency of the traditional methods in natural gas process, a new-type of dehydration unit for natural gas was briefly described and its basic structure and working principles were presented.We got the parameters distribution in the supersonic separator by getting the reasonable assumption,geometric model and time averaged equations in tensor form. From the results,a shock wave is found between-400 mm and-200 mm which is consistent with the experimental results. |
