Modelling of wall-bounded flows near a cylinder-bed junction in turbulent flow conditions using an IDDES turbulence model to asses initial particle entrainment

Due to the presence of a monopile in a turbulent flow swirling vortices, known as horseshoe vortices, can form upstream of the structure near the cylinder-bed junction. Those vortices then travel downstream of the cylinder as they are being dragged along with the current. The horseshoe vortices can scoop up bed material surrounding the cylinder,...

Detached Eddy Simulation applied to three-dimensional aerodynamic full car simulations in motorsport

Detached Eddy Simulation is investigated as a potential method to improve the design process in the Aerodynamic Prototype Development Department of Porsche Motorsport. Detached Eddy Simulation is a CFD method that combines the scale resolving capabilities of Large Eddy Simulation with the low cost modelling of the Reynolds-Averaged Navier-Stokes...

Development of a hybrid RANS-LES model for transitional boundary layers

High-fidelity hybrid RANS/LES methods are unable to accurately predict the transition from laminar to turbulent boundary layer flows. Usually resulting in an incorrect prediction of boundary layer characteristics. In this study, a hybrid RANS/LES model was developed for transitional boundary layer flows. The transitional kkL-omega turbulence...
