This project demonstrates how SimScale can be used to assess the aerodynamic behavior of sports devices. In this case a football is investigated with regards to the turbulent behavior of the surface pattern. The mesh is generated using the hex-dominant mesh operation of SimScale including a local mesh refinements as well as boundary layer generation on the surface of the ball.
The simulation is carried out incompressible, steady-state with the k-omega SST turbulence model. The simulation was run on an 8-core machine where it took around 20 minutes to complete.
The results can be viewed in SimScale’s online post-processor or with a local post-processing software. The results show nicely that the surface pattern affects significantly the turbulent structures in the airflow around the ball. This influences the trajectory and the stability of the ball and is one of the reason why the surface patches are constantly optimized.
