Fluid-Structure interactions with Navier- and full-slip boundary conditions

Antonín Češík, Malte Kampschulte, Sebastian Schwarzacher

We show the existence of weak solutions to the fluid-structure interaction problem of a largely deforming viscoelastic bulk solid with a viscous fluid governed by the incompressibl…

On bifurcations and traction forces on an obstacle in incompressible flow

Jakub Cach, Karel Tůma, Jan Blechta +1

A systematic numerical investigation of flow-regime transitions in the two-dimensional incompressible Navier-Stokes flow past a confined circular cylinder is presented. For a fixed…

Thermal effects in fluid structure interactions

Sourav Mitra, Sebastian Schwarzacher

In this article we consider two different heat conducting fluids each modelled by the incompressible Navier-Stokes-Fourier system separated by a non-linear elastic Koiter shell. Th…

Regularity estimates of a fluid-free surface evolution

Malte Kampschulte, Joonas Niinikoski, Sebastian Schwarzacher

In this work the evolution of a fluid droplet in vacuum is considered. This means that the surface tension and the fluid forces are in equilibrium at the free boundary. The fluid i…

Thermo-elastodynamics of nonlinearly viscous solids

S. Almi, R. Badal, M. Friedrich +1

In this paper, we study the thermo-elastodynamics of nonlinearly viscous solids in the Kelvin-Voigt rheology where both the elastic and the viscous stress tensors comply with the f…

Geometric re-meshing strategies to simulate contactless rebounds of elastic solids in fluids

J. Fara, S. Schwarzacher, K. Tůma

The paper deals with the rebound of an elastic solid off a rigid wall of a container filled with an incompressible Newtonian fluid. Our study focuses on a collision-free bounce, me…
