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.

一套高速相机的应用三维粒子跟踪测速（3D-PTV）以及表面变形测量的要求。该系统将使我们对复杂分离流的理解取得重大进展，这些复杂分离流与从启动风力涡轮机叶片到鸟类大小的无人机（称为微型飞行器（MAV））到旋转系统中的分离诱导过渡等应用有关。与三维PTV，同时体积测量的三维，时间分辨的速度场和梯度张量将首次实现。通过将动量平衡应用于解析数据集，可以获得完整的动压场以及沿给定叶片或机翼的沿着截面力。3D-PTV的实施将是加拿大的第一次，并将对未来风力涡轮机、MAVS和下一代压缩机的发展产生直接影响。例如，我们对这些流动的更好理解将有助于降低风力涡轮机的制造和维护成本，并有助于正确选址。微型飞行器将用于各种各样的应用，如用于警察、气象学、搜索和救援、国防和污染物扩散的遥感，它将受益于涡流控制，以提高其阵风容忍度。为了最大限度地提高生产率，该摄像机系统还可以通过光流技术进行同步表面变形测量，从而深入了解耦合的流体-结构相互作用问题。
