On failure of linear Hooke's law at turbulence occurrence

摘要

An analytical expression of improved Hooke's law for gases connecting the pressure change with a change in density is obtained. The influence of acoustic density perturbations on the stability of laminar flow of a viscous heat-conducting gas in a flat channel is defined. This effect is taken into account via the nonlinear pressure additive that is included in a Hooke's law. The results of computing experiment are presented.
