摘要

本文研究了超流体氦在 U 型圆柱通道中的动力学实验数据。文中描述了一个实验单元以及调查、参数测量和所得数据处理的方法。当在加热器附近施加热通量时，会出现蒸汽，界面表面会以恒定的频率产生宏观振幅的规则振荡。给出了界面表面位置和相应参数对时间的依赖关系。所获得的实验结果将根据之前获得的解析解进行解释。

The dynamics of the interfacial surface of helium II–vapor in a U-shaped channel

The paper considers experimental data on the dynamics of superfluid helium in a U-shaped cylindrical channel. An experimental cell and a methodology for investigations, parameter measuring, and obtained data processing are described. When a heat flux is applied near the heater, vapor can appear, and the interfacial surface executes regular oscillations of macroscopic amplitude with a constant frequency. The dependences of the interfacial surface position and the corresponding parameters on time are given. The obtained experimental results are interpreted based on the earlier obtained analytical solution.

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.
