A mechanism of turbulence arising in viscous heat-conducting gas is considered. It is found, that linear Hooke’s Law connecting the change of pressure and relative volume deformation is broken. The small acoustic disturbances of density, which take place in a viscous heat-conducting gas flow, produce nonproportional pulsation of pressure, thus turbulence appears. The results of computing and experiments are presented.

Keywords: turbulence, viscous heat-conducting gas.
