Noninvasive Measurement of Velocity, Pressure, and Temperature in Unseeded Supersonic Air Vortices

Physical probes can significantly perturb the flow under study during in situ fluid measurements. Stimulated Raman gain spectroscopy (SRGS) is one of many laser methods under development for a variety of noninvasive diagnostic applications.

Description
Summary:Physical probes can significantly perturb the flow under study during in situ fluid measurements. Stimulated Raman gain spectroscopy (SRGS) is one of many laser methods under development for a variety of noninvasive diagnostic applications. The SRGS method uses coherent Raman scattering from N... in unseeded air and simultaneously produces averaged measurements at a single spatial point of multiple velocity components, along with static pressure and temperature.
