The goal of this project is to provide measurements of gas temperature in a nanosecond repetitively pulsed (NRP) discharge that is initiated within various combustion mixtures. These temperature measurements are necessary to validate chemical kinetics codes that require this temperature as an input. Several approaches are currently being considered and include spontaneous Rayleigh/Raman scattering, Optical Emission Spectroscopy (OES) and coherent anti-Stokes Raman scattering (CARS). Parallel measurements on another project will focus on determining the chemical composition of the discharge. The ultimate goal is to compare the combined measurements of temperature and chemical composition with numerical predictions. The candidate will therefore pursue these temperature measurements while collaborating with other researchers within the team.
