Homogenization of the compressible Navier-Stokes equations via two-scale convergence in perforated domains

Markus Gahn, Kuntal Bhandari, Šárka Nečasová +1

We study the homogenization of the compressible isentropic Navier-Stokes equations in periodically perforated domains where the size of the obstacles is of the same order as the di…

Weak-strong uniqueness and low Mach number limit for a viscous compressible fluid around a rotating body

Thomas Eiter, Šárka Nečasová, Florian Oschmann

We study the flow of an isothermal compressible Newtonian fluid around a body that performs a (time-independent) rigid motion. We derive a weak-strong uniqueness principle, and sho…

Maximal regularity for a compressible fluid-structure interaction system with Navier-slip boundary conditions

Kuntal Bhandari, Imene Aicha Djebour, Šárka Nečasová

We investigate a fluid-structure interaction system in which the dynamics of the fluid is described by the compressible Navier-Stokes equations, while the elastic structure is mode…

Steady weak solutions to an inflow/outflow driven compressible fluid-structure interaction problem

Boris Muha, Šárka Nečasová, Milan Pokorný +2

We study a stationary 3D/2D fluid-structure interaction problem between an elastic structure described by the linear plate equation and a fluid described by the compressible Navier…

Dissipative solutions to a Beris-Edwards type model for compressible active nematic liquid crystals

Kuntal Bhandari, Apala Majumdar, Šárka Nečasová

We study the hydrodynamics of compressible active nematic liquid crystals in a three-dimensional and bounded domain, with a nonlinear viscosity tensor and nonhomogeneous boundary d…

On dissipative turbulent solutions to the compressible anisotropic Navier-Stokes equations in unbounded domains

Ondřej Kreml, Šárka Nečasová, Tong Tang

Inspired by Abbatiello, Feireisl and Novotný, we prove the global existence of dissipative turbulent solution for the compressible Navier-Stokes equations with anisotropic viscous…
