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 ... An efficient simultaneous reconstruction technique for ... ... . 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.

Tomographic Particle Image Velocimetry - Tomographic PIV or Volumetric PIV is a technique which enables the instantaneous measurement of all three velocity components in a complete 3D measurement ... In this study, a high-speed tomographic particle-image velocimetry (HS-TPIV) setup is used to measure the velocity field in an internal combustion engine (ICE) at an engine speed of 1,500 rpm and at a temporal resolution of 10° crank angle (CA) in a maximum measurement volume of 50x8x83 mm³. The HS-TPIV results are validated using high-speed Tomographic Particle Image Velocimetry Using Colored Shadow Imaging by Meshal K Alarfaj, Master of Science King Abdullah University of Science & Technology, 2015 Tomographic Particle image velocimetry (PIV) is a recent PIV method capable of reconstructing the full 3D velocity field of complex flows, within a 3-D volume. For Particle image velocimetry (PIV) has been heralded as an accurate means of measuring velocimetry information for the study of flow-field phenomena. Many discoveries have been made utilizing the diagnostic technique; however, most of the work has been focused on two dimensions. In turbulent flows, time-resolved three-dimensionality is more often fact than exception. COMPRESSED MOTION SENSING FOR TOMOGRAPHIC PARTICLE IMAGE VELOCIMETRY STEFANIA PETRA ABSTRACT.In previous work [PS14,PSS13] we analyzed representative ill-posed scenarios of Tomographic Parti- cle Image Velocimetry (Tomo PIV) [ESWvO07] with a focus on conditions for unique volume reconstruction. Large-scale tomographic particle image velocimetry. Tomographic particle image velocimetry (tomographic PIV or Tomo-PIV) is a new PIV technique which allows for measurements of three-dimensional instantaneous flow fields in a complete volume (see Elsinga et al. 2006).
