Time-resolved Piv and Pressure Measurements of Oscillating and Pulsating Flow in a Rapid Expansion

Separating oscillating and pulsating flows in an internal adverse pressure gradient geometry are studied experimentally. Time-resolved PIV measurements and simultaneous pressure measurements reveal that, in oscillating flow, during the accelerating portion of the cycle, the flow remains attached in spite of a very large adverse pressure gradient. During the decelerating portion of the cycle, th...

Full-field pressure from snapshot and time-resolved volumetric PIV

This paper deals with pressure estimation from snapshot and time-resolved three component (3C) volumetric PIV data using Taylor’s hypothesis, an Eulerian and a pseudo-Lagrangian approach. The Taylor’s hypothesis approach has been shown to provide accurate results for pressure in the case of 3C planar PIV data with an appropriate choice of convection velocity (de Kat and Ganapathisubramani, 2013...

Time-resolved tomo-PIV measurements to study 3D coherent structures in a pulsed jet in cross-flow

The recent tomo-PIV technique is presented and apply to a pulsed jet in cross-flow. This technique gives the instantaneous three-dimensional velocity field in a fat sheet (typically the depth of the measurement volume is a tenth of the other dimensions). The results presented here show the applicability of the technique to the characterization of a complex three-dimensional flow.

PIV measurements of a microchannel flow

A particle image velocimetry (PIV) system has been developed to measure velocity fields with order 1-lm spatial resolution. The technique uses 200 nm diameter flow-tracing particles, a pulsed Nd: YAG laser, an inverted epi-fluorescent microscope, and a cooled interline-transfer CCD camera to record high-resolution particle-image fields. The spatial resolution of the PIV technique is limited pri...

PIV measurements of flow in a centrifugal blood pump: time-varying flow.

Measurements of the time-varying flow in a centrifugal blood pump operating as a left ventricular assist device (LVAD) are presented. This includes changes in both the pump flow rate as a function of the left ventricle contraction and the interaction of the rotating impeller and fixed exit volute. When operating with a pulsing ventricle, the flow rate through the LVAD varies from 0-11 L/min dur...
