A high-speed Camera for measuring High velocity flows for hydraulics research

已要求提供资金购买一台高速摄影机，用于测量阿尔伯塔大学水资源小组水力研究中的高速水流。 拟议中的相机将具有每秒2000帧的速度和1000 × 1000像素的图像分辨率。 拟议中的相机将支持博士的研究计划。Zhu和N. Rajaratnam在他们的研究：1）高速水射流的空气夹带，2）水中多相射流的动力学，以及3）明渠中的湍流。此外，拟议中的相机将支持水资源小组的其他研究人员研究雨水下水道中的快速流动瞬变、冰塞固结和浪涌传播等。建议的相机将是兼容的，可以很容易地集成到现有的速度测量（PIV）系统，从而允许测量高速流。六名学生计划使用它在他们的研究一旦它是可用的。平均而言，在前5年，10 - 15名研究生将在他们的研究中使用它。

Funds are requested to purchase a high-speed camera for measuring high-velocity flows in hydraulic research in the Water Resources group at the University of Alberta. The proposed camera will have a speed of 2000 frames per second and an image resolution of 1000 by 1000 pixels. The proposed camera will support research programs of Drs. D. Zhu and N. Rajaratnam in their studies of: 1) air entrainment by high-speed water jet, 2) dynamics of multi-phase jets in water, and 3) turbulent flows in open channels. In addition, the proposed camera will support other researchers in the Water Resources group in studying rapid flow transients in stormwater sewers, ice jam consolidation and surge propagation, among others. The proposed camera will be compatible with and can be readily integrated into the existing velocity measurement (PIV) system, thus allow the measurement of high velocity flow. Six students are scheduled to use it in their research once it is available. On average, in the first 5 years 10 - 15 graduate students will use it in their research.
