On the P-23 Extreme Fluids Team at Los Alamos National Laboratory, we apply high-resolution diagnostics to study fluid dynamics problems in extreme environments, such as shock-driven mixing and variable-density decaying turbulence. The team is composed of Los Alamos staff, postdocs, and students.
At the Gas Shock Tube Facility, we apply high-resolution velocity and density field diagnostics (PIV and PLIF) to study the development of shock-driven hydrodynamic instabilities. The movie, below, is experimenta data that shows the passage of a Mach 1.5 shock (cartoon, orange line) passing through an SF6 gas curtain and the resulting growth of the instabilities in the gas curtain. Each image is about 50 µs apart, and the movie runs for 1250 µs after shock passage through the initial conditions. Experimental data were taken by Greg Orlicz and Sridhar Balasubramanian.
