Steady Motion of a Self-Propelled Body in a Viscous Fluid: Dirichlet Boundary Conditions with Nonzero Flux

Šárka Nečasová, Arnab Roy, Ana Leonor Silvestre

We study the steady self-propelled motion of a rigid body immersed in an incompressible viscous fluid occupying an exterior domain in . In a body-fixed reference fram…

Existence of weak solutions for incompressible fluid-Koiter shell interactions with Navier slip boundary condition

Claudiu Mîndrilă, Arnab Roy

We study a three-dimensional fluid-structure interaction problem describing the motion of an incompressible, viscous fluid coupled with a deformable elastic shell of Koiter type th…

Steady Self-Propelled Motion of a Rigid Body in a Viscous Fluid with Navier-Slip Boundary Conditions

Sarka Necasova, Arnab Roy, Ana Leonor Silvestre

We investigate the steady self-propelled motion of a rigid body immersed in a three-dimensional incompressible viscous fluid governed by the Navier-Stokes equations. The analysis i…

Fluid-Structure Interaction with Porous Media: The Beaver-Joseph condition in the strong sense

Tim Binz, Matthias Hieber, Arnab Roy

This article considers fluid structure interaction describing the motion of a fluid contained in a porous medium. The fluid is modelled by Navier-Stokes equations and the coupling…

Multilayered fluid-structure interactions: existence of weak solutions for time-periodic and initial-value problems

Claudiu Mîndrilă, Arnab Roy

We study the interaction between incompressible viscous fluids and multilayered elastic structures in a 3D/2D/3D framework, where a 3D fluid interacts with a 2D thin elastic layer,…
