Three-Dimensional Fluid Flow Measurement Techniques with Applications to Biological Flows
The accuracy of plenoptic and tomographic particle image velocimetry (PIV) experimental methods is measured by simulating three-dimensional flows and measuring the errors in the estimated versus true velocity fields. Parametric studies investigate the accuracy of these methods by simulating a range …

Tomographic PIV measurement of coherent dissipation scale structures
… flow between counter rotating impellers, using Tomographic Particle Image Velocimetry (TPIV). TPIV software was developed, with a novel approach permitting a significant reduction in processing time, and a series of numerical accuracy studies contributing to the fundamental understanding of this …

Measurement of three-dimensional coherent fluid structure in high Reynolds number turbulent boundary layers
… by our ability to simulate and measure them. Tomographic Particle Image Velocimetry (TPIV) is a recently developed technique for direct measurement of fluid velocity within a 3D region. This allows new insight into the topological structure of turbulent boundary layers. Increasing Reynolds …

Empirical mode decomposition applied to planar and volumetric velocity field measurements of a supersonic separated flow
… supersonic base flow which were obtained using particle image velocimetry. The resulting two-dimensional intrinsic mode functions reveal the various length scales associated with different regions of the flowfield. Coherent streamwise-oriented structures of different scales were detected …
