Femtosecond Laser Electronic Excitation Tagging Velocimetry in a Mach 6 Ludwieg Tube

Stephen W. Grib et al.

Summary: This study conducted nonintrusive velocity measurements using FLEET technique on air and nitrogen flows at 1 kHz, finding that the measured velocities differed by 1-2% from the computed values. Additionally, the velocity gradient along the shock layer was measured and analyzed at several locations.

10 kHz molecular tagging velocimetry in a Mach 4 air flow with acetone vapor seeding

Mark Gragston et al.

Summary: In this study, 10 kHz molecular tagging velocimetry (MTV) was conducted in a M-infinity = 4 Ludwieg tube using a partial pressure of acetone as a tagging agent. Despite using air as the operating gas, the emitted MTV line showed long-lasting characteristics, which is advantageous for flow tagging. The results indicate the potential of the technique for effective velocimetry in supersonic tunnels and its accessibility for Nd:YAG pulse burst laser systems.

Hypersonic N2 boundary layer flow velocity profile measurements using FLEET

Jonathan L. Hill et al.

Summary: This study utilized femtosecond laser electronic excitation tagging (FLEET) velocimetry in the boundary layer of an ogive-cylinder model in a Mach-6 Ludwieg tube, investigating the effects of model tip bluntness and unit Reynolds number on velocity profiles. The potential of FLEET velocimetry for understanding the dynamics of laminar and turbulent boundary layers in hypersonic flows was demonstrated.
