The authors carried out a simulation of the flow of gases with different densities in the Simcenter STAR-CCM+ software package. The objects of study are jets of helium, carbon dioxide and air, injected into the cocurrent flow of air moving in the channel through an axisymmetric nozzle. A mathematical model based on the averaged Reynolds equations for a mixture of incompressible gases closed by a standard linear k – ε-model is described, the results of calculating the fields of average velocities are presented. The calculation method was validated according to the data of physical experiments published in the open press.
