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

在艾伯塔大学水资源组的水力学研究中，为测量高速流动，需要资金购买一台高速照相机。拟议中的相机将具有每秒2000帧的速度和1000 x 1000像素的图像分辨率。该相机将支持朱博士和拉贾拉特南博士的研究项目：1)高速水射流卷吸空气，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、冰塞固结和涌浪传播等。该摄像机将与现有的速度测量(PIV)系统兼容，并可以很容易地集成到PIV系统中，从而实现对高速流动的测量。一旦它可用，六名学生计划在他们的研究中使用它。平均而言，在头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.
