New insights in unsteady three dimensional flows and their interactions with airfoils and bluff bodies

非定常三维流动与翼型和钝体的相互作用在航空航天、风能生产和运输等许多重要应用中有着重要的影响。这些现象是多物理现象，以复杂的流动和非定常空气动力学为特征。我的研究计划的最终目标是加强目前关于这些现象的基础知识，并将结果转移给其他研究人员和最终用户(加拿大行业和政府)。*拟议的研究将在舍布鲁克大学(UDES)的大型风洞中进行。它的封闭试验段为1.82m1.82m，最高气流速度为32m/S，将评估雷诺数和攻角等不同参数的影响。我们将研究非定常尾迹的时空动力学，即涡旋结构的识别和发展。测量将使用一些高科技设备记录，如热线风速仪(HWA)和层析粒子图像测速仪(Tomo-PIV)。将培训不同级别的高素质人员(HQP)(博士、硕士和本科生)。他们将在加拿大的许多高科技领域获得高要求的技能和专业知识，作为流体力学的实验方法。这些HQP将在一个激励和动态的环境中工作，作为UDES的机械工程系，那里提供补充计划来获得横向能力。**

The interactions between unsteady three-dimensional (3D) flows with airfoils and bluff bodies have a significant impact in many important applications as the aerospace and wind energy production and transportation. These phenomena are multi-physics and characterized by a complex flow and unsteady aerodynamics. The ultimate goal of my research program is to enhance the current fundamental knowledge regarding these phenomena and to transfer the outcomes to other researchers and end-users (Canadian industries and government).******The proposed research will be conducted in the large wind tunnel at the Université de Sherbrooke (UdeS). It has a closed test section of 1.82 m1.82 m and a top speed of the air flow is 32 m/s. The effect of different parameters, as the Reynolds number and the angle of attack, will be evaluated. The spatiotemporal dynamics of the resulted unsteady wake will be investigated, namely the identification and development of the vortex structures. The measurements will be recorded using some high tech equipment as the Hot Wire Anemometry (HWA) and Tomographic Particle Image Velocimetry (Tomo-PIV).******Highly qualified personnel (HQP) at different levels (PhDs, Masters and Undergraduate students) will be trained. They will gain highly demanded skills and expertise in many high technology sectors in Canada as experimental methods in fluid mechanics. These HQP will work in a stimulating and dynamic environment as the Department of mechanical engineering at the UdeS where complementary programs are offered to acquire transversal competencies. **
