Abstract

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.

U 形通道中氦 II 蒸气界面的动力学特性

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。
