Abstract

Femtosecond Laser Electronic Excitation and Tagging (FLEET) is an unseeded molecular tagging technique that has been demonstrated for velocimetry in hypersonic flows in large scale facilities, mostly at 1kHz repetition rate. This work presents a demonstration of FLEET at 60kHz, allowing for continuous measurement of high-speed flows with enhanced temporal resolution. Two-dimensional velocimetry was performed using a subsonic nitrogen flow at atmospheric pressure using a commercially available femtosecond laser system. The system was also deployed in a hypersonic wind tunnel at Texas A&M University to demonstrate the high-frequency FLEET feasibility for high speed air flows.
