Wheel rotation in external aerodynamics computations
Páleš, Patrik ; Vančura, Jan (referee) ; Čavoj, Ondřej (advisor)
The aim of the master’s thesis is an investigation of volume mesh quality, turbulent models and models of rotation and their influence on aerodynamic coefficients of rotating wheels. Mesh independence study and near-wall prism layer modelling are also of high importance. Subsequently, the appropriate turbulent model is used for research of wheel rotation on drag and lift on a front and rear axle of the vehicle compared to the stationary case.
Analysis of the effect of rotation of the wheels on the aerodynamic characteristics of the vehicle
Škrášek, Roman ; Čavoj, Ondřej (referee) ; Vančura, Jan (advisor)
This diploma thesis deals with modeling and CFD calculation of aerodynamic characteristics of vehicle, influenced by loaded or unloaded tires and boundary conditions applied on this tires. These calculations are combined with three types of variable rear body shape of DrivAer vehicle. There is a complete analysis and evaluation of the effects of these factors.
