Flow properties of superfluid He II (stability of oscillating boundary layer flow) and quantum turbulence (temporal decay of counterflow turbulence) above 1.3 K are studied using second sound attenuation technique. Flows of rotating superfluid ³He phases and of He II in zero temperature limit are investigated in collaboration with Finland and UK. Experiments on high Rayleigh number cryogenic thermal convection are under preparation.
