The dissertation presents the results of experimental studies of kinetic and dynamic processes in superfluid helium and its solutions of 3He-4He. The conditions for the appearance of the boundary instability between the phases of the stratified solution and the excitation of convective turbulence in the volume of the solution are investigated. The temperature dependence of the mobility of the interphase boundary at ultra-low temperatures has been studied. A transient turbulent flow regime of a superfluid liquid was detected at temperatures below 0.7 K. The influence of van der Waals forces on the temperature of the superfluid transition of atomic helium films on the graphite was studied.
