The influence of the spoiler on the sport car aerodynamics and stability

Abstract

The aerodynamic as well as the vehicle stability is directly related to the vehicle design. This research deals with the determination of the influence of the spoiler in the vehicle aerodynamic and stability. It was created the virtual model of the sport car in the proportion 1:1 with and without spoiler, which was tested in the software package ANSYS/Fluid Flow (CFX). The presence of the spoiler contributes to the higher value of the drag force, while at the same time decrease the lift force. The developed testing approach, indicates on the fact, how the testing process can be speed‐up, and due to this, to reduce the price of the development of the new product, what leads to the better competitiveness on the market.
