Summary

RESULTS OF EXPERIMENTAL INVESTIGATION OF HELIUM II FLOW CRISIS IN POROUS MEDIA ARE INTRODUCED. IT IS SHOWN THAT ONE MUST KNOW STRUCTURAL CHARACTERISTICS OF THE POROUS MEDIA IN ORDER TO PREDICT CRITICAL VELOCITIES OF HELIUM II SUPERFLUID COMPONENT. ANALYSIS OF HELIUM II VISCOSITY EFFECT ON A FLOW THROUGH A POROUS MEDIUM HAS SHOWNTHAT IT IS NECESSARY TO ALLOW FOR CHANNEL SIZE DEPENDENCE OF HELIUM II VISCOSITY. THE LATTER DEPENDENCE AND ITS USABILITY LIMITS ARE OFFERED.
