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

Bum Ja Jin, Å Ã¡rka NeÄasovÃ¡, Florian Oschmann +1

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

Global well-posedness and time-decay estimates of the Navier-Stokes equations in exterior domains for critical data

Tongkeun Chang, Bum Ja Jin

It is well known that the Navier-Stokes equations have unique global strong solutions for standard domains when initial data are small in $L_{σ}^{n}$ . Global well-posedness has been ex…

Global existence of non-Newtonian incompressible fluids in half space with nonhomogeneous initial-boundary data

Tongkuen Chang, Bum Ja Jin

In this study, we investigate the global existence of weak solutions of non-Newtonian incompressible fluids governed by (1.1). When $u_0 \in \dot B^{Î±-\frac{2}{p}}_{p,q}({\mathbb…
