STAR-CCM+ was used to perform the aerodynamic analysis of a Wilson soccer ball in order to better understand its side force effect. The image shows streamlines in the wake behind the soccer ball.
STAR-CCM+ is unrivaled in its ability to quickly and efficiently tackle complex geometries. Shown is an analysis with STAR-CCM+ displaying the complex flow patterns as a result of the accidental deployment of a thrust reverser on a business jet while in-flight.
Streamlines on a trap wing : simulations were computed using the steady state, coupled flow solver with implicit integration and second order discretization and using the SST (Menter) k-ω turbulence model. This work was done as part of a drag prediction workshop.

RANS models include; Spalart-Allmaras, a range of K-Epsilon models, both standard and SST variants of the K-Omega model as well as two Reynolds stress models. Where laminar-turbulent transition occurs, STAR-CCM+ has the option to use the Gamma-Re-Theta model to model its onset.
When more accurate capture of turbulent flow structures is required such as in the study of aeroacoustics, STAR-CCM+ has a number of options for both LES and DES modeling. For LES, the Smagorinsky, dynamic Smagorinsky and WALE subgrid models are available. For DES, the latest delayed and improved delayed detached eddy simulation models are available for both Spalart-Allmaras and K-Omega SST variants. Finally, the synthetic eddy method for the specification of realistic inflow boundary conditions is available for both LES and DES.
