In the article, the usability of standard two-parameters models of turbulence for numerical simulation of a vortex tube is discussed. Both k − ε and k − ω turbulence models were checked for subsonic air flows into the vortex tube channel. The main attention was paid to the development of the mesh, the simplicity of the implementation of simulation, and the physical concordance of the model results. Simulations performed by rhoPimpleFoam and sonicFoam solvers using k-ε and k-ω turbulence models gave similar results. The choice was made in favor of the k − ε model.
