Stochastic forcing in hydrodynamic models with non-local interactions
Pavel Ludvik, Vaclav Macha
The hydrodynamical model of the collective behavior of animals consists of the Euler equation with additional non-local forcing terms representing the repulsive and attractive forc…
Compressible fluid inside a linear oscillator
Vaclav Macha
We use Feireisl-Lions theory to deduce the existence of weak solutions to a system describing the dynamics of a linear oscillator containing a Newtonian compressible fluid. The app…
Dimension reduction for the compressible Navier-Stokes system with density dependent viscosity
Matteo Caggio, Vaclav Macha
We consider a compressible Navier-Stokes system for a barotropic fluid with density dependent viscosity in a three-dimensional time-space domain where $…
Low stratifucation of the complete Euler system
Jan Březina, Václav Mácha
The present paper takes advantage of the concept of dissipative measure-valued solutions to show the rigorous derivation of the Euler-Boussinesq (EB) system that has been successfu…
Low stratification of a heat-conducting fluid in time-dependent domain
Ondřej Kreml, Václav Mácha, Šárka Nečasová +1
We study the low Mach number limit of the full Navier-Stokes-Fourier system in the case of low stratification with ill-prepared initial data for the problem stated on moving domain…
Non-uniqueness of delta shocks and contact discontinuities in the multi-dimensional model of Chaplygin gas
Jan Březina, Ondřej Kreml, Václav Mácha
We study the Riemann problem for the isentropic compressible Euler equations in two space dimensions with the pressure law describing the Chaplygin gas. It is well known that there…
