Understanding The Dynamics Of Droplets And Turbulence
7/20/2017
Turbulent flows laced with particles can be found everywhere, and include fuel droplets in combustion engines, airborne pollen, and water droplets in clouds. Even though they have been studied often, questions still remain that have to do with the particles’ inertia prohibiting them from following turbulence flow, making the Navier-Stokes equations insufficient for solving their equations. This white paper presents a project studying the dynamics of inertial droplets in a turbulent flow in a well-controlled environment. Measurements of droplet size distribution and turbulent dispersion rate in this study are done with interferometric particle imaging (IPI) and phosphorescent tagging techniques.

Development Of Background-Oriented Schlieren For NASA Langley Research Center Ground Test Facilities
6/13/2017
This paper provides an overview of recent wind tunnel tests performed at the NASA Langley Research Center where the Background-Oriented Schlieren (BOS) technique was used to provide information pertaining to flow-field density disturbances. The facilities where the BOS technique was applied included the National Transonic Facility (NTF), Transonic Dynamics Tunnel (TDT), 31-Inch Mach 10 Air Tunnel, 15-Inch Mach 6 High-Temperature Air Tunnel, Rotor Test Cell at the 14×22 Subsonic Tunnel, and a 13-Inch Low-Speed Tunnel.
