The paper presents the problem of numerical calculation of turbulent flow in a channel with an obstacle based on the COMSOL MULTIPHYSICS software package. Turbulent flow in a channel with an obstacle is a complex physical process that can be studied using numerical simulations, including the use of software packages such as COMSOL Multiphysics. Turbulence in a channel flow with an obstacle is characterized by vortex structures, three-dimensional motion and significant drag caused by the interaction of the flow with the obstacle. To simulate such a flow, various turbulence models can be used, such as the k−e model, the k−w model or the LES (large eddy method) models, as well as turbulence models based on the Reynolds equations (RANS). COMSOL Multiphysics provides the ability to simulate turbulent flow in a channel with an obstacle. The user can create channel geometry, add obstacles, set boundary conditions, select an appropriate turbulence model, and run flow simulations. As a result of modeling, it is possible to obtain data on speed, pressure, turbulent parameters and other characteristics of the flow. These data allow a deeper understanding of the physical process of real flow in a channel with an obstacle, as well as optimization of the design to improve flow characteristics. In the numerical calculation of turbulent flow in the channel, standard k−e and SST models were used. The results obtained using the COMSOL MULTIPHYSICS package were compared with experimental data.
