Properties of Moving Electron Bubbles in Superfluid Helium
Abstract
It is well known that the Bernoulli effect modifies the shape of gas bubbles moving through a liquid. In this paper we investigate the influence of the Bernoulli pressure on the shape of electron bubbles moving through superfluid helium. We show that an electron bubble moving through liquid at zero pressure becomes unstable when its velocity reaches approximately 47 m s-1. In addition, the change in shape contributes significantly to the variation of the bubble mobility with velocity.
