Non-linear waves in fluids near the critical point

TL;DR

This paper presents a non-linear model based on Landau-Ginzburg theory that predicts phase transition waves and solitary kinks near the critical point, highlighting differences between isothermal and isentropic wave behaviors.

Contribution

Introduces a novel non-linear model for phase transition waves near the critical point, incorporating both conservative and dissipative cases.

Findings

Predicts phase transition waves and solitary kinks near the critical point

Shows differences between isothermal and isentropic wave behaviors

Applies to both conservative and dissipative systems

Abstract

A non-linear model associated with a Landau-Ginzburg-like behavior in mean field approximation forecasts phase transition waves and solitary kinks near the critical point. The behavior of isothermal waves is different of the one of isentropic waves as well in conservative cases as in dissipative cases.
