Surveys of data on turbulent thermal counterHow in superfluid 'He-'He mixtures of molar concentrations X = 4.6%, 7.2% and 11 .(I% have been collected for the temperature range between 1.30 and 1.70 K. The non-steady character of thermal counterflow in mixtures, caused by the drag on the 'He particle

We have studied superfluid 3He-4He mixtures quenched into nonequilibrium states inside the miscibility gap by means of second sound . From the results for the second sound velocity we conclude that the superfluid density in the metastable state is well described by extrapolation from equilibrium val
