Acquisition of a tomographic PIV system for enhancement of flow-structure interaction studies
Abstract
This DURIP proposal targets the acquisition of a tomographic Particle Image Velocimetry (tomo-PIV) system for volumetric measurements of three components of velocity within flow fields. Tomo-PIV is a state-of-the-art diagnostic technique that is a culmination of a number of recent novel developments in 3D object reconstruction. The motivation of this proposal is to bring this unique capability to bear on three research projects related to DOD applications involving precision drop systems (funded by the Army Research Office), safe landing of planes on aircraft carriers (funded by the Office of Naval Research), and flutter of wings in the presence of wind shear (funded by the Airforce Office of Scientific Research). A key goal in all of these projects is to develop an understanding of the flow mechanisms leading to the development of force and moment on objects embedded in the flow. The tomographic capability will enable a powerful analysis in which the contribution of individual flow structures to the pressure acting on the surface of objects is quantified. The analysis is based on measuring the volumetric distribution of flow sources of pressure in connection with Green s function solution of Poisson s equation for pressure in incompressible flows. The results will produce powerful insights into the flow mechanisms leading to the generation of surface pressure, and consequently the flow force and moment acting on objects. Such insights are essential for the development of physics-based models for guiding the design and/or the control of aerodynamic systems of significance to DOD. The tomographic capability will also bring the education of undergraduate and graduate students at MSU to the cutting edge of experimental fluid mechanics and aerodynamics through involvement in the related research projects and also the use of this state-of-the-art equipment in an existing course on experimental fluid mechanics.
