We have decided to discontinue the publication of preprints on our preprint server as of 1 March 2024. The publication culture within mathematics has changed so much due to the rise of repositories such as ArXiV (www.arxiv.org) that we are encouraging all institute members to make their preprints available there. An institute's repository in its previous form is, therefore, unnecessary. The preprints published to date will remain available here, but we will not add any new preprints here.

Dimension reduction for compressible viscous fluids
Peter Bella, Eduard Feireisl and Antonín Novotný
Abstract
We consider the barotropic Navier-Stokes system describing the motion of a compressible viscous fluid confined to a cavity shaped as a thin rod $\Omega_\epsilon = \epsilon Q \times (0,1)$, $Q \subset \mathbb{R}^2$. We show that the weak solutions in the 3D domain converge to (strong) solutions of the limit 1D Navier-Stokes system as $\epsilon \to 0$.
