The aerodynamic drag of an EV is the major energy consuming vehicle attributes, an EV requires less cooling flow, and can have a flat underbody, which potentially can improve the overall aerodynamics of the vehicle. The flow around the wheels and in the wheelhouses is a significant part of the total aerodynamic drag. Different aerodynamics concept vehicles have been studied in the past and shown in the automotive industry, the flow around wheels is managed and smoothen. They key for success is to manage the flow and keep the car functional and attractive. This master thesis project combines a through study of the historical and current aerodynamics concept cars regarding wheelhouse flows, comparing different rim designs, quantifying different features around the wheels or improvements in terms of drag reduction and range increase and finally a CFD study of DrivAer with implementing features/improvements.

Nyckelord: Wheel, EV , Drag reduction, Wheelhouse, Wheelhouse covered, Rim design, Aerodynamic drag, Deflector.
