Verified numerical computation of solutions for the stationary Navier-Stokes equation in nonconvex polygonal domains

Abstract

We propose a method to enclose solutions for the stationary Navier-Stokes equation in nonconvex polygonal domains. Our method is based on an infinite dimensional Newton-type formulation by using the finite element method with constructive error estimates and fixed point theorems. Numerical examples related to the step flow problems in $L$-shape domain are presented.
