This paper investigates the influence of inertial processes on the of small disturbances and the properties of the critical flow of continuos media. The intertial processes may stem from heat and mass exchange on the component two-phase flow. Since almost all the models of a flow medium take the form of hyperbolic, quasi-linear systems of partial-differential equations, the mathematical background of the critical flow and the propagation of linear disturbances, for this type of equations, is presented. The problem of discontinuous solutions and its possible influence on the critical flow has been discussed Finally, some important differences concerning linear waves in dispersive and non-dispersive systems are discussed.
