Selection of a turbulence model in mathematical modeling of propeller operation

mathematical modeling is widely used to solve applied problems in the field of shipping safety. Modeling of ship motion includes modeling the operation of the propeller, which creates hydrodynamic processes in the stern area. The quality of the modeling results depends on the mathematical models used. Turbulence arising from the rotation of the propeller is described using a special turbulence model. Currently, there are three main mathematical models of turbulence: k-ε, k-ω and Reynolds stress equations. The most suitable model can be selected by conducting a numerical experiment. This article presents the results of a numerical experiment aimed at comparing the above turbulence models and their analysis using the example of solving a specific problem.
