Sammanfattning
This diploma work is based on two parts. The first part is a study of the equipment for the Chalmers wind tunnel with the aim to specify what needs improvement in order to setup a fully functional aerodynamics laboratory. Further it includes the conceptual design of a sting that should carry a car model when using moving ground. The second part contains a study of the flow around a wheel in a wheel house cavity in moving and stationary ground condition. The aim of the study was to try to give further explanation to the change in the drag coefficient so often reported from such studies. The conclusion of the study was somewhat fuzzy owing to the pour function of the experimental equipment. However some good flow visualizations came about that lead to a better understanding of the flow field around the front wheels. The experiment was carried out in the Wind tunnel of Chalmers University of Technology.
