3D Particle Tracking Velocimetry using Synthetic Aperture Imaging
3D visualization of fluid flow is of critical significance to a number of applications ranging from micro-scale medical devices to design of ships and airplanes. Of the various techniques currently used to visualize flow fields, particle image velocimetry (PIV) offers great advantages because of the high resolution quantitative results it provides. The feasibility of using synthetic aperture (S...
متن کاملA genetic algorithm particle pairing technique for 3D velocity field extraction in holographic particle image velocimetry
This research explores a novel technique, using Genetic Algorithm Particle Pairing (GAPP) to extract threedimensional (3D) velocity fields of complex flows. It is motivated by Holographic Particle Image Velocimetry (HPIV), in which intrinsic speckle noise hinders the achievement of high particle density required for conventional correlation methods in extracting 3D velocity fields, especially i...
متن کاملPhantom validation of 4D flow: independent validation of flow velocity quantification using particle imaging velocimetry
Background 4D phase contrast magnetic resonance blood flow measurements (4D PC-MR) is a promising tool for clinical assessment of cardiac function, but lack of independent validation may limit clinical adoption. Previous validation studies are limited by lack of pulsatility [1,2] or by the need of a post hoc correction factor to compensate for differences in experimental setup between 4D PC-MR ...
متن کاملHigh Dynamic Velocity Range Particle Image Velocimetry Using Multiple Pulse Separation Imaging
The dynamic velocity range of particle image velocimetry (PIV) is determined by the maximum and minimum resolvable particle displacement. Various techniques have extended the dynamic range, however flows with a wide velocity range (e.g., impinging jets) still challenge PIV algorithms. A new technique is presented to increase the dynamic velocity range by over an order of magnitude. The multiple...
