This research aims at improving our understanding and modelling of turbulent flows encountered in important industrial applications, such as the flows around airplanes, wind turbines or inside turbo engines and hydro turbines. The flows considered are near surfaces and decelerate under the influence of pressure variations. We are seeking a better understanding of the fundamental properties of these flows and an improvement of turbulence models used in industrial flow simulation codes. For that purpose, we use theoretical methods and ideas, precise simulations of carefully chosen flows, and advanced analysis of numerical and experimental databases. Our research will 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). It 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.

这项研究旨在提高我们对重要工业应用中遇到的湍流的理解和建模，例如飞机，风力涡轮机或涡轮发动机和水轮机内部的流动。所考虑的流动是近表面的，并在压力变化的影响下减速。我们正在寻求更好地了解这些流动的基本性质和改进的湍流模型中使用的工业流动模拟代码。为此，我们使用理论方法和思想，精心选择的流的精确模拟，以及数值和实验数据库的高级分析。我们的研究将支持工业界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、发电用水力和风力涡轮机）。这将有助于特别是在这些产品的设计和数字建模。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。
