Our Projects

Research involving turbulence interactions with fluid media and its boundaries.

High-Speed Two-Phase Flows

Studying the dynamics of particle-laden high-speed flows.

Jet Noise Reduction

Developing novel approaches to thrust-efficient noise reduction for supersonic jet propulsion.

Aero-Thermo-Dynamics

Studies on the aero-thermo-dynamics in excited and/or perturbed high-speed boundary layers.

Turbulence Dynamics in Transient Flows

Decomposition, analysis, and characterization of turbulence induced by shock-driven transients.

Shockwave Boundary-Layer Interaction

Dynamics of turbulence and shock interactions in high-speed boundary layers.

AeroAcoustics

High-fidelity measurements and dynamical system analysis of aeroacoustic phenomenon.

the Facilities

Industrial-scale facilities in academic surroundings provide for nimble and responsive capabilities to study complex fluid phenomena ranging from sub-sonic to hyper-sonic.

Tri-Sonic Wind Tunnel

A 12"-by-12" blow-down wind tunnel facility capable of flows from Mach 0.3 to Mach 5.0. Optical access for non-intrusive diagnostics. Rapid air-system recharge allowing 4-6 runs/hour typical. Capable of supporting combusting flows, laser and aero-optical engagement, free-release separation testing, and powered inlet/nacelle configurations.

Anechoic Jet Laboratory

Gaseous propane or methane fuel jet test rig provides for continuous operation at total temperatures reaching 1000 K at Mach 1.5 for a nominal jet diameter of 2". Fully anechoic configuration for acoustic field measurements. Precision controlled traverse system for detailed investigation of flow phenomena with modern laser-based diagnostics.
