This diploma thesis is focused on CFD simulation of two platooning DrivAer cars with varying bodyworks. CFD models are made for bodywork variants Estateback, Fastback and Notchback, which are solved by k-epsilon turbulent model. Influence of rear body design on platooning and aerodynamics characteristics is analyzed.

This thesis deals with CFD simulation of platooning vehicles and their aerodynamic characteristics, created in Star CCM+ software. The main focus is on their aerodynamic drag dependency on different spacing between vehicles which allowed to evaluate the most energy efficient distance for platoon of vehicles. Furthermore, the procedure how to calculate the fuel consumption is described for set of variables.

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.
