DURIP: Acquisition of instruments for very high-speed three dimensional velocity and profilometry measurements
Abstract
The main objective of the proposed work is the acquisition of a very high-speed laser, two CMOS cameras, and supporting instruments system. The resulting diagnostics will take advantage of the latest development in instrumentation to form a custom state-of-the-art instrument that will be very flexible and modular to perform three dimensional (3D), high-speed, scanning PIV and 3D profilometry in very steep liquid-gas disturbances that are encountered in all aspects of naval environments that range from ship hydrodynamicsto combustion. Initially the system will allow resolving turbulence statistics near rough liquid-air surfaceas well as characterizing air entrainment mechanisms from bulk turbulence. Thanks to the system modularity, it will integrate seamlessly into existing suite of instruments in the PI~s laboratory, enabling the future development of 3D scanning stereo-PIV and initiation of tomographic PIV development below highly disturbed interfaces or any other applications that require high temporal resolution. Finally, the PI has experience deploying advanced laser diagnostics at other institutions and proposes to collaborate with other PIs within ONR by bringing this instrument to their laboratories.
