Abstract
Results of simulation study of evolution of solitary intensive second-sound waves spreading in superfluid helium are presented. Quantitative description was carried out on the basis of equations of hydrodynamics of superfluid turbulence (HST). HST equations with second-order accuracy (relative parameter deviation from equilibrium) were written for the cases of planar, cylindrical, and spherical geometries. The system of equations was solved using the disruption decay technique. Calculations were carried out for the temperature of undisturbed helium Т0 = 1.4 K. Simulation results were compared with experimental data.
