In this paper, the capabilities of two-parameter turbulence models for modeling the flow around a flat plate and a two-dimensional terrain model are investigated. The mathematical basis of the simulation is based on the Reynolds-averaged stationary Navier-Stokes equations. The numerical solution of the basic equations was carried out using the OpenFOAM package. Comparison of the results of numerical calculations with the corresponding experimental data allows us to conclude that the good agreement on the velocity profiles and the size of the reverse current zone corresponds to the k-ε- RNG turbulence model implemented in the OpenFOAM package.
