Homogenization of a relaxed compressible viscous two-phase fluid model in a domain with very tiny holes

Florian Oschmann, Florian Wendt

We study an approximate system for the compressible Navier-Stokes-Korteweg equations in a bounded domain periodically perforated by small obstacles. As the size of the obstacles de…

Elastic properties of cubic silicon carbide with Si vacancies

Carlos P. Herrero, Eduardo R. Hernandez, Gabriela Herrero-Saboya

We investigate how silicon vacancies modify the elastic response and mechanical stability of cubic 3C-SiC. Our approach employs path-integral molecular dynamics simulations, includ…

Homogenization of regularized Oldroyd-type fluids

Florian Oschmann, Jonas Sauer

We study homogenization of a regularized viscoelastic Oldroyd-type model in a periodically perforated bounded domain. The system describes an incompressible non-Newtonian fluid cou…

Homogenization of compressible Navier-Stokes equations under a hard sphere pressure law

Nilasis Chaudhuri, Florian Oschmann

We consider the compressible time-dependent Navier-Stokes equations in a bounded perforated domain in dimensions two and three. Provided the perforations are small enough, we show…

Weak-strong uniqueness and low Mach number limit for a viscous compressible fluid around a rotating body

Thomas Eiter, Šárka Nečasová, Florian Oschmann

We study the flow of an isothermal compressible Newtonian fluid around a body that performs a (time-independent) rigid motion. We derive a weak-strong uniqueness principle, and sho…

Qualitative/quantitative homogenization of some non-Newtonian flows in perforated domains

Richard M. Höfer, Yong Lu, Florian Oschmann

In this paper, we consider the homogenization of stationary and evolutionary incompressible viscous non-Newtonian flows of Carreau-Yasuda type in domains perforated with a large nu…
