Ketana Teav (MASc Candidate)

Ketana is working on filtered Rayleigh scattering (FRS) for non-intrusive laser-based temperature measurements in confined and particle laden flows. An extension of Rayleigh scattering, FRS is advantageous for combustion thermometry as it filters the purely elastic component of the sample's scattering signal, which is contaminated with noise from large particles and surfaces. However, the relationship between the remaining signal and temperature is not as definitive as in conventional RS due to temperature-dependent broadening of the scattering spectrum. Simultaneous RS and FRS measurement therefore will be performed in clean flows to investigate the monotonicity and linearity of the FRS signal relative to RS. This work will enhance the experimental diagnostic tools of the lab, advancing its research capabilities, while allowing Ketana to explore the fundamental nature of the universe, to unveil its secrets, and perhaps finally to learn what it means to be human.
