Statphysのため8月に来日されるFlorian Kogelbauerさんが京大に来訪されて以下のセミナーを行います。ご興味のある方のご来聴を歓迎いたします。

日時: ８月１４日（月） １５：００ から １７：００

場所: 京大 理学研究科５号館(物理学教室) ４０１号室

講師： Florian Kogelbauer (ETH Zurich)

講演題目： Exact Hydrodynamics from Kinetic Theory

講演要旨：
The closure problem for kinetic equations constitutes one of the fundamental questions in thermodynamics. Based on the refined spectral theory of several kinetic models, involving a finite-dimensional Grad system, the Boltzmann-BGK equation and the Shakhov model, we give exact closure relations and transport operators for the hydrodynamic moments (density, velocity and pressure). This allows us to derive a new, non-local fluid model for gaseous fluid in the linear regime, which extends classical models such as the Navier—Stokes equation.
