Hydrodynamic Limit with Geometric Correction of Stationary Boltzmann Equation

Analysis of PDEs 2015-10-19 v5

Abstract

We consider the hydrodynamic limit of a stationary Boltzmann equation in a unit plate with in-flow boundary. We prove the solution can be approximated in LL^{\infty} by the sum of interior solution which satisfies steady incompressible Navier-Stokes-Fourier system, and boundary layer with geometric correction. Also, we construct a counterexample to the classical theory which states the behavior of solution near boundary can be described by the Knudsen layer derived from the Milne problem.
