The results of numerical modeling of turbulent airflow in a room using the computational fluid dynamics approach to solve the Reynolds-averaged Navier-Stokes equation for a fluid are presented. First, a two-dimensional model was studied; the focus is on mesh refinement, the effect of mesh topology, and the influence of the turbulence model. The structured grid results were found to be in better agreement with available experimental measurements. Dimensionless velocities for various turbulence models are presented and compared: standard k-ε, standard k-ω, RNG k-ε, k-ω SST. The results explain that all turbulence models produce almost identical results.
