Particle Image Velocity Measurements of Undular and Hydraulic Jumps
Measurements of the mean and turbulent flow fields in undular and hydraulic jumps have been acquired with single-camera particle image velocimetry PIV . Three Froude numbers, ranging from 1.4 to 3.0, were studied, and in each case data were collected at numerous streamwise locations. The data from these streamwise locations were subsequently compiled into spatially dense 80,000 grid points “mos...
متن کاملSound field separation with sound pressure and particle velocity measurements.
In conventional near-field acoustic holography (NAH) it is not possible to distinguish between sound from the two sides of the array, thus, it is a requirement that all the sources are confined to only one side and radiate into a free field. When this requirement cannot be fulfilled, sound field separation techniques make it possible to distinguish between outgoing and incoming waves from the t...
متن کاملInverse Source Identification based on Acoustic Particle Velocity Measurements
A general applicable acoustic source identification method is the inverse frequency response function technique (IFRF). In the standard IFRF method acoustic pressures measured on a grid in the nearfield of the acoustic source are used. To relate the measured field pressures to the normal velocities on the surface of the source, a transfer matrix is calculated with a boundary element method. The...
متن کاملVelocity Field Measurements Using Digital Particle Image Velocimetric System
Particle Image Velocimetry (PIV) is a non-intrusive technique for simultaneously measuring the velocities at many points in a fluid flow. Several case studies related to nuclear reactor were performed with the PIV system. Some of the cases like flow in circular tube, submerged jet, natural convection in a water pool and Fluidic Flow Control Device (FFCD) used in advanced accumulator of Emergenc...
متن کاملNear-wall velocity measurements by Particle-Shadow-Tracking
We report a new method to measure the velocity of a fluid in the vicinity of a wall. The method, that we call Particle-Shadow Tracking (PST), simply consists in seeding the fluid with a small number of fine tracer particles of density close to that of the fluid. The position of each particle and of its shadow on the wall are then tracked simultaneously, allowing one to accurately determine the ...
