Battery Electric Vehicles (BEV) are central to automotive manufacturers meeting their CO2 emissions obligations. Also, the sale of new internal combustion engine cars is being phased out. Navigating this transition requires customer acceptance with range a key factor, which is strongly influenced by aerodynamic drag.While BEVs provide new opportunities for lower drag underfloors SUVs must still deliver off-road performance with a rear suspension which is cost-effective, leading it to be exposed to the airflow: a drag and range penalty. Requirements for articulation and off-road robustness mean that conventional undertrays or covers are not effective solutions.This project aims to (1) identify the interactions between underfloor flow, rear suspension, diffuser, wheel and rear wake systems; (2) develop flow control strategies (e.g., vortex generators, deployable, deformable and morphing surfaces) reducing the drag impact of the suspension system, optimising the benefits of a rear diffuser as part of a wake control strategy.

电池电动汽车（BEV）是汽车制造商履行其二氧化碳排放义务的核心。此外，新的内燃机汽车的销售正在逐步淘汰。虽然纯电动汽车为降低地板下的阻力提供了新的机会，但SUV仍然必须通过具有成本效益的后悬架提供越野性能，这导致它暴露在气流中：阻力和范围损失。对关节和越野鲁棒性的要求意味着传统的底盘或覆盖物不是有效的解决方案。本项目旨在（1）确定地板下流动、后悬架、扩散器、车轮和后尾流系统之间的相互作用;（2）开发流动控制策略（例如，涡流发生器、可展开的、可变形的和变形的表面）减少悬架系统的阻力影响，优化作为尾流控制策略的一部分的后扩散器的益处。
