Instrumentation for 2D and 3D Holographic Particle Image Velocimetry in Axial Turbomachines

Abstract

This DURIP grant provided the instrumentation needed for measuring the flow structure and turbulence in axial turbomachines. The main components are: i. A dual head, injection seeded, 300 mi/pulse, Nd YAG laser; ii. The optical components for assembling two dimensional Particle Image Velocimetry (PIV) and three dimensional holographic PIV systems; iii. The components for a dedicated holographic PIV reconstruction system, including the optics and image acquisition systems. These instruments are integral ports of our effort to develop a laboratory for measuring the flow structure within axial turbomachines and to use the data for addressing a series of turbulence modeling issues.
