Extending relative entropy for Korteweg-Type models with non-monotone pressure:large friction limit and weak-strong uniqueness

Giada Cianfarani Carnevale, Jan Giesselmann

In this paper we study weak-strong uniqueness and singular relaxation limits for the Euler--Korteweg and Navier--Stokes--Korteweg systems with non monotone pressure. Both weak-stro…
