CFD Simulation of Wake Behind Adidas Brazuca Soccer Ball at 50mph


STAR-CCM+ was used to study the behavior of Brazuca at 50 mph using CFD. The model is courtesy of and is a representative model of the actual ball. We meshed the Brazuca in STAR-CCM+ using the Overset Mesh technology and ran a Detached Eddy Simulation (DES) of the flow over the stationary ball at 50mph. A DES simulation is necessary to accurately capture the turbulent eddies in the wake region. In the animation below, you can clearly see that while there is still some unsteadiness and asymmetry in the wake region behind the ball, the wake doesn’t wildly fluctuate and oscillate from one side to the other.
