ABSTRACT

It is shown that the obtained improved Hooke's law for viscous heat-conducting gas is actually a law describing the emergence of turbulence in this environment. It is noted that when analysing of the emergence of turbulence in the boundary layer it is necessary to take into account the compressibility of the medium and the dissipation of energy in a stream. The results of computing experiment are presented.

Key words: turbulence, viscosity, law of turbulence emergence, viscous heat-conducting gas.
