Abstract

Various steady states of 3He–4He quantum solutions are studied. The hydrodynamic Hamiltonian is used to take into consistent account the interaction between quasiparticles. The chemical potential, osmotic pressure, and the inert mass of the gas of impuritons are calculated. The Knudsen effect is studied in the quantum gas of impuritons by taking into account the interaction and nonquadratic energy-momentum relation. The results of theoretical investigations are compared with the experimental data.
