Summary

It is found that the waveform of a thermal pulse in the second sound wave mode loses its dependence on heating time in the case of strong heating. Only a limited, small amount of thermal energy is transported in this mode. In such a situation, dense quantized vortices are generated and accumulate in the vicinity of the heating surface to form a thermal boundary layer which has a large temperature gradient. The rest of the energy is slowly transported in a diffusive process or is consumed upon phase transition of the helium II.
