Wind tunnels are an important tool that are used for automotive performance testing. The wind tunnels are used to produce airflow conditions that a vehicle experiences with accuracy and repeatability. Vehicle testing performed in wind tunnels is used to characterize performance measures such as aerodynamics, which is important for improving fuel consumption/emissions and vehicle stability. Most full-scale automotive test facilities are designed to simulate ideal conditions such as a that occurring when a vehicle passes through still air. However, on-road driving conditions are subject to turbulence, cross flow or wind gusts, that can degrade a vehicle's performance. Aiolos Engineering Corporation is a Canadian company that is located in Toronto, Ontario. Aiolos is a world leader in the design and construction of full-scale wind tunnels and test facilities. In this collaborative partnership between Aiolos and Prof. Hanson's research group (in the Department of Mechanical Engineering, York University), a novel active unsteady flow and turbulence generation system for automotive wind tunnels to better simulate on-road wind conditions will be researched and developed. Measurements of the unsteady flow and turbulence produced by the active system will be carried out. The effect of geometric and motion parameters of the active system on the resulting flow fields will be studied to determine suitable combinations to better model the airflow conditions often experienced by vehicles on the road. In the long term the research supports improved vehicle performance and the Canadian competitive advantage in wind tunnel design. The proposed project will also support the training of MASc students in experimental fluid dynamics, wind tunnel testing and dynamic systems, which are relevant skills in demand by industry sectors including automotive, aerospace, wind engineering and energy.

风隧道是用于汽车性能测试的重要工具。风隧道用于产生汽车具有准确性和可重复性的气流条件。在风隧道中进行的车辆测试用于表征诸如空气动力学之类的性能指标，这对于改善燃油消耗/排放和车辆稳定性非常重要。大多数全尺寸的汽车测试设施旨在模拟理想条件，例如当车辆通过静止空气时发生的情况。但是，道路驾驶条件可能会遭受湍流，跨流或风阵的影响，这些驾驶条件可能会降低车辆的性能。 Aiolos Engineering Corporation是位于安大略省多伦多的加拿大公司。 Aiolos是全面风隧道和测试设施的设计和建设的世界领导者。在Aiolos和Hanson教授研究小组（约克大学机械工程系）之间的这种合作伙伴关系中，将研究和开发一种用于汽车风隧道的新型活跃的非稳定流量和湍流产生系统，以更好地模拟道路风条件。将进行主动系统产生的不稳定流量和湍流的测量。将研究活动系统的几何和运动参数对所得流场的影响，以确定合适的组合，以更好地建模道路上车辆经常经历的气流条件。从长远来看，研究支持了改善的车辆性能和风洞设计中的加拿大竞争优势。 拟议的项目还将支持MASC学生在实验流体动力学，风洞测试和动态系统方面的培训，这些动态系统是行业领域的相关技能，包括汽车，航空航天，风工程和能源。
