水的速度分布测量和流动显示对于预测诸如暴雨下水道中的猛烈间歇泉和管道中的分层流等现象是重要的。使用可视化技术，如PIV（粒子图像测速），PTV（粒子跟踪测速）和LDV（激光多普勒测速）计算流场和应变率分布等特征。然而，这种技术需要昂贵的设置和一次性可用的昂贵的晶种颗粒。本文首先提出了一个负担得起的水PIV技术，使用简单的现成的马铃薯淀粉和激光二极管。其次，我们评估了智能手机用于低速水PIV的能力。最后，计算结果表明，抛物线的速度分布的层流和活塞型轮廓的近湍流，验证了我们的索赔。
The measurement of velocity distribution and flow visualization of water is important for predicting phenomena, such as violent geyser in a storm sewer and stratified flow in a pipe. Flow features such as velocity field and strain rate distribution are calculated using visualization techniques such as PIV (particle image velocimetry), PTV (particle tracking velocimetry), and LDV (laser Doppler velocimetry). However, such techniques require expensive setups and one-time usable expensive seeding particles. This article first proposes an affordable water PIV technique using simple off-the-shelf potato starch and laser diodes. Secondly, we assess the capability of smartphones for low-speed water PIV. Finally, the results show the parabolic velocity profile for laminar and piston type profile for the near turbulent flow, validating our claims.
