Experimental measurements are predominantly conducted using laser Doppler anemometry (LDA) [5,77], hot wire anemometry (HWA) [7] and particle image velocimetry (PIV) techniques [65,67,68]. Show abstract Study of the short-circuit flow and circulation flow's impact on separation performance of ...
The technique is therefore referred to as tomographic particle image velocimetry (tomographic-PIV). The reconstruction is performed with the MART algorithm, yielding a 3D array of light intensity discretized over voxels. The reconstructed tomogram pair is then analyzed by means of 3D cross-correlation...
Particle Image Velocimetry (PIV)Computer Fluid Dynamics (CFD)In recent years, minimum quantity lubrication (MQL) machining is regarded as a promising method for reducing machining cost and cutting fluid, while improving cutting performance. However the effectiveness and the working principle of MQL are...

2. Particle Image Velocimetry 2.1. Working Principle Particle Image Velocimetry (PIV) is used to measure the deformation law of surface soil. The principle of PIV flow field measurement is to input a certain amount of tracer particles into the flow field first. The tracer particles are required...
water jet; square nozzles; computational fluid dynamics (CFD); particle image velocimetry (PIV); constant-velocity core1. Introduction Hydraulic excavation [1,2,3,4] is the primary mechanized technology to excavate lotus roots from mud fields in China. Its working principle is to use the jet ...
Then a particle image velocimetry (PIV) based self-developed experimental observation platform is established, and the effectiveness of the proposed method is verified. Research results indicate that, in the high-speed turbulent environment, a large pressure difference existed in the bubble tail, which...
Particle image velocimetry (PIV) is an optical and contactless measurement method for analyzing fluid blood dynamics in cardiovascular research. The main challenge to visualization investigated in the current research was matching the channel material’s index of refraction (IOR) to that of the fluid....
