...intensity distribu-tion. The method is therefore referred to as tomo-graphic particle image velocimetry (tomographic-PIV) ... Single sensor fiber-based high-speed tomographic particle ... ... . Tomographic PIV experiment performed in the cavitation tunnel of CNR-INSEAN on a propeller model for wake analysis using a double-cavity Nd-YAG laser (2 X 200 mJ/pulse at 12.5 Hz) and four Imager ... Particle Image Velocimetry is used to evaluate an entire plane of motion. If the particle density is high and the location of a single particle cannot be tracked, the displacement of particles is then measured by statistical means (PIV). The flow regime is subdivided into small areas of investigation. The first two articles where the working principles an ... Tomographic PIV: Propeller wake analysis (CNR-INSEAN ... ... . The flow regime is subdivided into small areas of investigation. The first two articles where the working principles and their application have been given were presented by Elsinga et al (2005a, 2005b) at the 6th international PIV symposium hosted at Caltech (USA), resulting in the seminal article Tomographic particle image velocimetry (Elsinga et al 2006b). 9TH INTERNATIONAL SYMPOSIUM ON PARTICLE IMAGE VELOCIMETRY - PIV'11 Kobe, Japan, July 21-23, 2011 Volume Segmentation Tomographic Particle Image Velocimetry I.B.

Tomographic particle image velocimetry of desert locust wakes: instantaneous volumes combine to reveal hidden vortex elements and rapid wake deformation. Richard J. Bomphrey. Richard J. Bomphrey. Department of Zoology, University of Oxford, South Parks Road, Oxford OX1 3PS, UK. Tomographic particle image velocimetry (Tomo-PIV) [1, 2] is used for volumetric velocity measurements in gas and liquid flows. In contrast to the stereoscopic PIV method [ 3 , 4 ], where three velocity components are measured in a planar cross-section of the flow, the Tomo-PIV method allows for three-component three-dimensional (3D, volumetric) velocity field measurements in the flow. 9TH INTERNATIONAL SYMPOSIUM ON PARTICLE IMAGE VELOCIMETRY - PIV'11 Kobe, Japan, July 21-23, 2011 Tomographic Particle Image Velocimetry using Pulsed, High Power LED Volume Illumination N.A.

Soria1 1Laboratory for Turbulence Research in Aerospace and Combustion, Department of Mech. and Aerospace Tomographic particle image velocimetry Tomographic particle image velocimetry (Tomo-PIV) was applied on a turbulent round air jet to quantitatively assess the accuracy of velocity gradients obtained in the self-similar turbulent region. The jet Reynolds number based on the nozzle diameter (d) was Re d = 3000.
