vertical instability

The steam-water two-phase flow instability in vertical parallel pipes was studied experimentally in the high pressure steam-water test loop.

在高压汽水回路上对垂直并联管中汽液两相流不稳定性进行了试验研究。

The surface waves of a liquid in a rigid fluid-filled container is excited by vertical sinusoidal oscillation. Faraday instability is one of the three classical hydrodynamic instability problems in fluid mechanics, with the two others being Rayleigh-Benard convection and Taylor-Couette flow.

竖直方向的受周期性外激励的充液容器的自由表面波问题&Faraday波问题是流体力学三大不稳定性难题之一（另外两个不稳定性问题是Rayleigh-Benard对流和Taylor-Couette流）。
