Rapid, Efficient And Three-Dimensional Optical Measurement: Leading A Transformation In Flow And Flo
Abstract
This proposal requests equipment needed for high-speed high-resolution planar and volumetric measurement of turbulent flows, in supp,ort of key Navy relevant research efforts in aeroacoustics, fluid dynamics, propulsion and cavitation. The requested equipment will,combine with our existing high-speed planar PIV system (acquired under the 2018 program) to enable time resolved volumetric turbulen,ce measurements with an order of magnitude improvement in efficiency and resolution. This will have a transformative effect on at le,ast 6 current and proposed Navy sponsored research efforts, revealing for the first time fine details of cavitation bubble collapse,near surfaces, of the formation and ingestion of transient disturbances in boundary layers, of the three-dimensional structure of tu,rbulence responsible for subconvective pressure fluctuations, for example. Furthermore, the requested systems will enable these meas,urements and more to be performed with an efficiency that will allow entirefunctional dependencies of the observed phenomena to be c,aptured. This equipment will be housed and supported by the Virginia Tech Stability Wind Tunnel, the VT advanced Power and Propulsio,n Lab, and the VT Cavitation, Propulsion and Multiphase Flow Laboratory. As such it will serve as the focus of research training in,an area of importance to the Navy for a large cohort of masters and PhD students. It will also serve as a focus for required undergr,aduate laboratory experiences in Ocean, Aerospace and Mechanical Engineering that will be collocated with these ONR research efforts,, impacting over 400 students per year.(Publicly Releasable)
