Volumetric PIV System for Investigation of Flow Field Dynamics and Their Control

Abstract

The understanding of the three-dimensional nature of turbulence is crucial to understand turbulent flows for the broad range of engineered applications involving them. A fundamental understanding of the fluid flow can not only lead to better engineering designs it can facilitate the ability to efficiently alter the flow through flow control applications. Instrumentation to be able to measure the three-dimensional velocity field in a volume through a tomographic technique is being requested here. This tomographic Particle Image Velocimetry (PIV) system will be an upgrade to an existing stereo PIV system, to help minimize costs, and will greatly enhance the PI’s ability to examine turbulent flow phenomena. Applications involving the proposed system will range from supersonic flow over open cavities to noise generation from jets to identifying drag producing events in turbulent boundary layers. Investigation of these applications will extend the volumetric velocity measurements by utilizing novel time dependent estimation techniques as well is in pressure Poisson solvers to augment the understanding. The use of the new volumetric PIV system is crucial to a better understanding and will allow for novel experiments in these applications in order to allow us to extend current knowledge.
