Existence of strong solutions for a system of interaction between a compressible viscous fluid and a wave equation

D Maity, A Roy, T Takahashi - Nonlinearity, 2021 - iopscience.iop.org
In this article, we consider a fluid–structure interaction system where the fluid is viscous and
compressible and where the structure is a part of the boundary of the fluid domain and is …

Motion of a rigid body in a compressible fluid with Navier-slip boundary condition

Š Nečasová, M Ramaswamy, A Roy… - Journal of Differential …, 2022 - Elsevier
In this work, we study the motion of a rigid body in a bounded domain which is filled with a
compressible isentropic fluid. We consider the Navier-slip boundary condition at the …

Global existence of weak solutions for a model of nematic liquid crystal-colloidal interactions

Z Geng, A Roy, A Zarnescu - SIAM Journal on Mathematical Analysis, 2024 - SIAM
In this paper, we study a mathematical model describing the movement of a colloidal particle
in a fixed, bounded three dimensional container filled with a nematic liquid crystal fluid. The …

Remark on the global null controllability for a viscous Burgers-particle system with particle supported control

M Ramaswamy, A Roy, T Takahashi - Applied Mathematics Letters, 2020 - Elsevier
This paper is devoted to study the controllability of a one-dimensional fluid-particle
interaction model where the fluid follows the viscous Burgers equation and the point mass …

Fluid–rigid body interaction in a compressible electrically conducting fluid

J Scherz - Mathematische Nachrichten, 2023 - Wiley Online Library
We consider a system of multiple insulating rigid bodies moving inside of an electrically
conducting compressible fluid. In this system, we take into account the interaction of the fluid …

On the motion of a body with a cavity filled with magnetohydrodynamic fluid

B Huang, V Mácha, Š Nečasová - Journal of Differential Equations, 2024 - Elsevier
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 …

Shallow water waves generated by a floating object: a control theoretical perspective

P Su, M Tucsnak - arXiv preprint arXiv:2108.05088, 2021 - arxiv.org
We consider a control system describing the interaction of water waves with a partially
immersed rigid body constraint to move only in the vertical direction. The fluid is modeled by …

Collision/No-collision results of a solid body with its container in a 3D compressible viscous fluid

BJ Jin, Š Nečasová, F Oschmann, A Roy - arXiv preprint arXiv:2210.04698, 2022 - arxiv.org
We consider a bounded domain $\Omega\subset\mathbb R^ 3$ and a rigid body $\mathcal
{S}(t)\subset\Omega $ moving inside a viscous compressible Newtonian fluid. We exploit the …

Stabilization of a rigid body in a viscous incompressible fluid

KD Do - Ocean Engineering, 2023 - Elsevier
This paper addresses the problem of global asymptotic and local exponential stabilization of
a rigid body inside a viscous incompressible fluid described by Navier–Stokes equations …
