Studying the influence of the turbulence model on the aerodynamic characteristics of a cruise missile model

The article presents the study of the turbulence model’s influence on aerodynamic characteristics of a cruise missile model obtained during numerical calculations conducted using ANSYS Fluent Release 2023R1 software. Three turbulence models (i.e. Spalart-Allmaras, realizable k-ε and SST k-ω), as well as three computational meshes with a different refinement in a boundary layer region, were investigated. The results were analyzed and compared to characteristics obtained experimentally in the low-speed aerodynamic tunnel at the Military University of Technology (Warsaw, Poland).
