Turbulence on the surface of cryogenic liquids in restricted geometry of experimental cell

Abstract

We report on results of experimental investigations of nonlinear phenomena on the surface of liquid hydrogen and helium. The experiments were carried out at temperature T=1.7 K for superfluid helium and at T=15 K for liquid hydrogen. Helium and hydrogen gases were condensed into the copper cup of inner diameter 30 mm (helium) and 60 mm (hydrogen) and depth 4 mm.
