National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Gaseous Laser Targets and Optical Diagnostics for Studying Compressible Hydrodynamic Instabilities.

DE200415006189

Publication Date	2001
Personal Author	Edwards, J.; Robey, H.; Mackinnon, A.
Page Count	12
Abstract	Explore the combination of optical diagnostics and gaseous targets to obtain important information about compressible turbulent flows that cannot be derived from traditional laser experiments for the purposes of V and V of hydrodynamics models and understanding scaling. First year objectives: Develop and characterize blast wave-gas jet test bed; Perform single pulse shadowgraphy of blast wave interaction with turbulent gas jet as a function of blast wave Mach number; Explore double pulse shadowgraphy and image correlation for extracting velocity spectra in the shock-turbulent flow interaction; and Explore the use/adaptation of advanced diagnostics.
Keywords	Optical diagnostics Laser targets Mach number Spectra Targets Turbulent flow Velocity Gaseous targets Turbulent flows Blast wave interactions Turbulent gas jet Compressible hydrodynamic instabilities
