Description

New insight into mechanisms that can help to make propulsion and power systems “greener” and more sustainable cannot be simulated or known a priori, it needs to be developed through the rigorous testing and quantification. Ultrafast laser diagnostics has a tremendous potential to provide precise scalar determination at these harsh test environments, where often steep gradients in temperature and species concentration exists and these quantities evolve on a rapid time scale due to the turbulence of the flow. In this talk, I will present the development of a unique polarization-sensitive coherent Raman imaging spectrometer, with synchronized high peak-power laser pulses on a femtosecond- and picosecond timescale, and show how it is capable of quantifying spatially correlated temperature in-situ these flows with an uncertainty of less than 1%.
