A collision result for both non-Newtonian and heat conducting Newtonian compressible fluids

TL;DR

This paper extends collision results for a solid in 3D compressible fluids to include non-Newtonian fluids and Newtonian fluids with temperature-dependent viscosities, broadening the understanding of fluid-solid interactions.

Contribution

It generalizes existing collision results to cover non-Newtonian and temperature-dependent viscosity fluids, which were not previously analyzed.

Findings

Collision results established for non-Newtonian fluids

Collision results extended to temperature-dependent Newtonian fluids

Broader applicability of fluid-solid interaction models

Abstract

We generalize the known collision results for a solid in a 3D compressible Newtonian fluid to compressible non-Newtonian ones, and to Newtonian fluids with temperature depending viscosities.
