Abstract

Wheel aerodynamics of passenger cars has recently been under close investigation due to its influence on the aerodynamic forces on the vehicle. In modern wind-tunnels the wheel rotation can be resembled close to reality, while, in their CFD development process, car manufactures rely on simplified models for considering rotating wheels. In this paper, model-scale generic and production wheels are investigated experimentally, in respect of the influence of geometry, camber and a brake disc. The data is used to assess the accuracy of CFD simulations using open-source software and their applicability in a manufacturer’s CFD process.
