基于物理模型的汽车空气动力学研究综述

Review of automotive aerodynamics research based on physical models

汽车空气动力学涉及到绕流湍流、流动稳定性、流动分离与控制、流固耦合及噪声等复杂且基础的流体力学问题。本文梳理了国内外学者基于汽车物理模型的空气动力学研究进展,介绍了前人在气动力、流场研究、流动控制、计算和实验的对标、多车空气动力学、污染、风噪等方面取得的研究成果,分析了研究存在的不足,并对未来汽车空气动力学研究方向进行了探讨和展望。

Automotive aerodynamics involves fundamental fluid dynamics problems such as turbulence flow past bluff bodies,flow instability,flow separation and control,fluid-structure interactions and noise,and so on.In this paper,we review the research progress of aerodynamics based on physical models at home and abroad,introduce the achievements of previous studies on aerodynamics,flow field research,flow control,calculation and experiment,multi-vehicle aerodynamics,pollution,wind noise,etc.,and investigate the shortcomings of the present studies.Finally,we discuss the research directions of vehicle aerodynamics in the future.
