The results obtained are compared with known experimental data with different pipe diameters. The purpose of this work is to test the ability of models to describe anisotropic turbulence. It is shown that the two-fluid model is more suitable for studying such flows.}, type={artykuł}, title={Comparison of the results for calculation of vortex currents after sudden expansion of the pipe with different diameters}, keywords={two-fluid turbulence model, sudden expansion, velocity fluctuation, intensity of fluctuations, gas resistance, quasi-periodic regime}, }
