Selection criteria for the compressible Euler equations: numerical study
Megala Anandan, Bahulayan Chalil Aravind, Mária Lukáčová-Medvid'ová +4
We numerically investigate selection criteria for dissipative weak solutions of the compressible Euler equations. Using the Kelvin-Helmholtz problem as a benchmark, we compare four…

On admissible solutions to the coupled Riemann problem with heat-flux discontinuity
Changsheng Yu, Tiegang Liu
We study the Riemann problem for the compressible Euler equations with a stationary coupling interface across which a discontinuity in the heat flux is prescribed. This coupling gi…

Oscillatory approximations and maximum entropy principle for the Euler system of gas dynamics
Eduard Feireisl, Mária Lukáčová-Medvid'ová, Changsheng Yu
We show that the measure-valued solutions of the Euler system of gas dynamics generated by oscillatory sequences of consistent approximations violate the principle of maximal entro…
