We present a numerical study of flow in a 2D chamber of a simplified industrial boiler. The study features multiple cases of flow with different inlet settings. The mathematical model is based on the incompressible Navier-Stokes equations and solved numerically by means of finite element method. The time discretization is semi-implicit and the resulting linear systems are solved using multigrid solver parallelized via OpenMP. The goal of this study is to provide reference data for a complex model of coal combustion that is being verified.
