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

Bum Ja Jin, Šárka Nečasová, Florian Oschmann +1

We consider a bounded domain $\hat{I}\text{c◯}\subset {\mathbb{R}}^3$ and a rigid body $\mathcal{S}(t)\subset \hat{I}\text{c◯}$ moving inside a viscous compressible Newtonian fluid. We exploit the roughness of the…
