摘要

改进车辆设计对于美观和确保更高的效率和更低的燃料消耗至关重要。本研究旨在提供一种计算方法来解决实际的物理工程问题:汽车的空气动力学。本研究的重点是利用开源软件OpenFOAM来研究一款SAE方程式赛车外部整流罩的气动效应。使用的车辆是拉夫拉斯联邦大学ZEUS小组的Z03型号。车队参加了SAE方程式的大学比赛,因此,在接下来的版本中改进车辆的空气动力学对车队来说是至关重要的,可以提高车辆的效率,从而使模型更具竞争力。为了便于分析,对阻力和升力气动系数进行了分析。系统地进行了汽车气动仿真,并与文献结果进行了比较,得到了令人满意的结果。

Computational simulation of an aerodynamic profile of a vehicle SAE formula type using OpenFOAM
Improving vehicle design is essential for esthetic reasons and ensuring better efficiency and lower fuel consumption. The present study intends to provide a computational approach to an actual physical engineering problem: the aerodynamics of automobiles. The focus of this study was to use the open-source software OpenFOAM to study the aerodynamic effects on the external fairing of a Formula SAE vehicle. The vehicle used was the Z03 model of the ZEUS team of the Federal University of Lavras (UFLA). The team participates in university competitions of Formula SAE and, therefore, an aerodynamic improvement of the vehicle for the following versions can be fundamental for the team, increasing efficiency of the vehicle, resulting in a model of greater competitiveness. For analysis purposes, the drag and lift aerodynamic coefficients are analyzed. A procedure for performing aerodynamic simulations of automotive vehicles was systematized, and, in addition, satisfactory results were found for the presented simulation in comparison with results found in literature.
