On the Motion of a Body with a Cavity Filled with Magnetohydrodynamic Fluid

Bingkang Huang, Václav Mácha, Šárka Nečasová

We study the dynamics of a coupled system, formed by a rigid body with a cavity entirely filled with magnetohydrodynamic compressible fluid. Our aim is to derive the global existen…

On time-periodic solutions to an interaction problem between compressible viscous fluids and viscoelastic beams

Ondřej Kreml, Václav Mácha, Šárka Nečasová +1

In this paper, we study a nonlinear fluid-structure interaction problem between a viscoelastic beam and a compressible viscous fluid. The beam is immersed in the fluid which fills…

Analysis of a system modelling the interaction between the motion of a spring and a viscous gas

Sabrine Chebbi, Václav Mácha, Šárka Nečasová

We are concerned with a one dimensional flow of a compressible fluid which may be seen as a simplification of the flow of fluid in a long thin pipe. We assume that the pipe is on o…

On the Motion of a Pendulum with a Cavity Filled with a Compressible Fluid

Giovanni Paolo Galdi, Václav Mácha, Šárka Nečasová +1

We study the motion of the coupled system, , constituted by a physical pendulum, , with an interior cavity entirely filled with a viscous, compressible flui…

Relative energy inequality and weak-strong uniqueness]{Relative energy inequality and weak-strong uniqueness for an isothermal non-Newtonian compressible fluid

Richard Andrášik, Václav Mácha, Rostislav Vodák

Our paper deals with three-dimensional nonsteady Navier-Stokes equations for non-Newtonian compressible fluids. It contains a~derivation of the relative energy inequality for the w…
