摘要：In a fluid with a non-monotonic state function, like van der Waals fluid, nonlinear waves usually appear. Besides the well-known classical waves like shock waves, rarefaction waves and contact discontinuities, phase transitions are also found with specified initial data. The characteristic feature of a subsonic phase transition is different from a Lax shock due to the non-monotonicity of the state function. We will introduce the admissible criterion of subsonic phase transitions and present the stability result of such nonlinear waves.
