摘要

摘要对来自容器的气流通过特征时间从 0.6 秒到 9 秒的各种结构的节流管进行了实验研究。根据节流管长度与其标称直径之比，确定了等效容器出口面积。结果发现，在流出过程中，容器内的气体温度降低了 10-15%，这一数值与假定该过程为绝热过程而得出的 60% 的理论估计值相差很大。根据测量容器内气体压力和温度的结果，提出了一种计算壁上热通量的方法。

Study of the transient gas outflow from a container

An experimental study of the flow of air from a container through throttling tubes of various configurations with characteristic times from 0.6 to 9 s was carried out. The equivalent container-outlet area was determined based on the ratio of the length of the throttling tube to its nominal diameter. It was found that during the outflow, the gas temperature inside the container decreased by 10–15 %, which value differs substantially from the theoretical estimate of 60 % obtained assuming that the process was adiabatic. Based on the results of measuring the gas pressure and temperature in the container, a method is proposed for calculating the heat fluxes on the walls.

期刊介绍： The journal Thermophysics and Aeromechanics publishes original reports, reviews, and discussions on the following topics: hydrogasdynamics, heat and mass transfer, turbulence, means and methods of aero- and thermophysical experiment, physics of low-temperature plasma, and physical and technical problems of energetics. These topics are the prior fields of investigation at the Institute of Thermophysics and the Institute of Theoretical and Applied Mechanics of the Siberian Branch of the Russian Academy of Sciences (SB RAS), which are the founders of the journal along with SB RAS. This publication promotes an exchange of information between the researchers of Russia and the international scientific community.
