Digital Holographic Piv for 3d Flow Measurement
We have developed a simple digital holographic PIV system for 3D measurement of turbulent and multiphase flow. This system records in-line holograms of tracer particles directly on a digital camera and reconstructs the 3D particle field numerically. Using a novel complex amplitude-based method, we are able to overcome the depth of focus problem and the speckle noise problem associated with the ...
متن کاملReconfigurable Rainbow PIV for 3D Flow Measurement
In recent years, 3D Particle Imaging Velocimetry (PIV) has become more and more attractive due to its ability to fully characterize various fluid flows. However, 3D fluid capture and velocity field reconstruction remain a challenging problem. A recent rainbow PIV system encodes depth into color and successfully recovers 3D particle trajectories, but it also suffers from a limited and fixed volu...
متن کاملDigital In-line Holographic PIV for 3D Flow Measurement
We present the design and implementation of a digital in-line holographic PIV system for 3D flow measurements. This system records in-line holograms of tracer particles directly on a CCD camera and numerically reconstructs the holograms. The 3D position of particles is extracted from the reconstructed particle images, and velocity field is then obtained using an advanced particle tracking algor...
متن کاملDevelopment of Piv Technique under Magnetic Fields and Measurement of Turbulent Pipe Flow of Flibe Simulant Fluid
An investigation of MHD effects on a Flibe (Li2BeF4) simulant fluid has been conducted under the US-Japan JUPITER-II collaboration program using “FLIHY” pipe flow facility at UCLA. The present paper reports a development of unique experimental techniques using aqueous solution of potassium hydroxide as a Flibe simulant. In order to apply a particle image velocimetry (PIV) technique for magnetic...
متن کاملThe Wall-PIV Measurement Technique for Near Wall Flow Fields in Biofluid Mechanics
This chapter describes the development of a new time resolved 3D PIV technique for near wall flow field measurements. This measurement technique, called wall-PIV, is based on Beer-Lambert’s law. It substitutes the classical PIV laser sheet by a diffuse, monochromatic full-field illumination that is limited to the near wall region by an absorbing molecular dye in the fluid. Aimed range of applic...
