Abstract

Starting from the full system of hydrodynamic equations for helium isotopic mixtures, the problem of temperature and concentration relaxation is solved. The limiting case of ultralow temperatures, when the contribution of thermal excitations can be neglected, is considered. A comparison with the experimental data is carried out.
