This research program concerns the study of turbulent flows by experimental and theoretical means. The flows considered are near surfaces and are decelerated or accelerated under the influence of pressure variations. They are simplified versions of flows encountered in important industrial applications, such as the flows around airplanes, wind turbines or inside turbo engines. Through experiments and advanced analysis of numerical and experimental databases of carefully chosen flows, we are seeking a better understanding of the fundamental properties of these flows in order to support industrial efforts in developing and improving products that play an important socio-economic role for Canada (aerial, terrestrial and marine vehicles, turbo engines, hydro and wind turbines for power generation). Our research will help especially in the design and numerical modelling of these products. It will also reinforce our research collaboration with international experts of turbulent flows and it will create an excellent environment for the training of highly qualified engineers, researchers and professors.

本研究计划涉及通过实验和理论手段研究湍流。所考虑的流动是近表面的，并且在压力变化的影响下被减速或加速。它们是重要工业应用中遇到的流动的简化版本，例如飞机周围的流动，风力涡轮机或涡轮发动机内部。通过对精心挑选的流动的数值和实验数据库进行实验和高级分析，我们正在寻求更好地了解这些流动的基本特性，以支持工业界努力开发和改进对加拿大发挥重要社会经济作用的产品（航空，陆地和海洋车辆，涡轮发动机，水力和风力发电涡轮机）。我们的研究将特别有助于这些产品的设计和数值建模。它还将加强我们与国际湍流专家的研究合作，并为培养高素质的工程师，研究人员和教授创造良好的环境。
