Instrumentation For Studies Of Molecular Energy Conversion For Efficient Control Of High-Speed Flow Fields

Abstract

To get necessary equipment to demonstrate and quantify the effect of controlling the amount of energy stored in the internal molecular energy modes on the high-speed flow field, in well characterized flows, for several flow geometries, including shock-boundary layer interaction flows, cavity flows, and base flows. This will be accomplished by (i) time-dependent, high sampling rate measurements of 2-D distributions of N2 and O2 vibrational temperatures (usingsingle-pump CARS) and CO2/N2 mixture ratio (using dual-pump CARS), (ii) translational temperature and flow velocity (using interferometric Rayleigh scattering), and (iii) time dependent 2-D distribution of O and N atom number density (using ps Two-Photon Absorption LIF) and metastable excited electronic.
