A set of high-speed cameras for the application of three-dimensional Particle Tracking Velocitry (3D-PTV) as well as surface deformation measurements is requested. This system will allow for significant advances in our understanding of complex separated flows associated with applications ranging from starting wind-turbine blades to bird-sized drones called Micro Aerial Vehicles (MAVs) to separation-induced transition in rotating systems. With 3D-PTV, simultaneous volumetric measurements of the three-dimensional, time-resolved velocity field and gradient tensor will be attainable for the first time. By applying a momentum balance to the resolved data set, access to the full dynamic pressure field as well as sectional forces along a given blade or wing will be possible. The implementation of 3D-PTV would be a first in Canada and would have immediate impact on the development of future wind turbines, MAVS and next-generation compressors. For instance our improved understanding of these flows would help reduce fabrication and maintenance costs of wind turbines as well as help with proper siting. MAVs, which will be used for a myriad of applications such as remote sensing for policing, meteorology, search and rescue, defence and pollutant dispersion, stand to benefit from vortex control to improve their gust tolerance. For maximum productivity, this camera system can also be arranged for simultaneous surface deformation measurements through optical-flow techniques, thus providing insight into coupled fluid-structure interaction problems.

请求一组用于应用三维粒子跟踪速度（3D-PTV）以及表面变形测量值的高速相机。该系统将允许我们理解与从启动风力涡轮叶片到称为微型航空车辆（MAV）到旋转系统中分离诱导的分离诱导的鸟类无人机相关的复杂分离流动的重要进展。使用3D-PTV，可以首次获得三维，时间分辨速度场和梯度张量的同时体积测量。通过将动量平衡应用于已解决的数据集，将有可能访问全动态压力场以及沿给定的刀片或机翼的截面力。 3D-PTV的实施将是加拿大的第一个，并将立即影响未来的风力涡轮机，MAV和下一代压缩机的发展。例如，我们对这些流量的提高理解将有助于降低风力涡轮机的制造和维护成本，并有助于适当的选址。 MAV将用于多种应用，例如用于警务，气象，搜索和救援，防御和污染物分散的遥感，可以从涡旋控制中受益，以提高其阵风的耐受性。为了最大程度的生产率，该相机系统也可以通过光流技术安排，以同时进行表面变形测量，从而提供了对耦合流体结构相互作用问题的见解。
