Towards single shot gas flow velocity and temperature measurements with coherent Rayleigh-Brillouin scattering
- View All
� 2019 by German Aerospace Center (DLR). Published by the American Institute of Aeronautics and Astronautics, Inc. We suggest and report progress towards the use of single shot coherent Rayleigh-Brillouin scattering (CRBS) as a gas flow velocity and temperature measuring technique, applicable to both atomic and molecular gases, as well as gas mixtures. CRBS has already been demonstrated to be the coherent analogue of spontaneous Rayleigh-Brillouin scattering in measuring the temperature, pressure, bulk and shear viscosity, speed of sound and polarizability of a gas or gas mixture. We are working towards the application of single shot CRBS as a gas flow measurement technique and its use in neutral or partially ionized gas flow environments.
