Car chassis diffuser
Kindl, Albert ; Balko, Marek (referee) ; Rudolf, Pavel (advisor)
Improving a car's aerodynamic properties can save fuel, increase range, or improve speed and handling. To achieve this, aerodynamic modifications and improvements are proposed to cars. The aim of this thesis is to describe a diffuser on an automotive chassis. The focus is mainly on the effect of its divergence angle on drag and lift. These dependencies are investigated on a simplified car model using CFD simulation in Ansys Fluent. The research section discusses the diffuser flow and losses, other important aerodynamic features and the importance of the diffuser in Formula 1 and passenger cars. The results of the thesis show the significant effect of the diffuser on the downforce and drag of the vehicle and indicate the important position of this element in the future of the automotive industry.
