Bio

I am currently a Mechanical Engineering graduate student at Stanford University pursuing a PhD. At the university, I work as a research assistant in the high-temperature gas dynamics laboratory. My current work involves novel concepts in laser spectroscopy. I pride myself in being self-motivated, detail oriented, and a team player.

  • Multi-parameter, kHz rate spectrally resolved NO PLIF in a supersonic jet OPTICS LETTERS Barnes, S. C., Lee, J., Clees, S., Vandervort, J. A., Strand, C. L., Hanson, R. K. 2026; 51 (4): 957-960

    Abstract

    Quantitative, high-bandwidth measurements of temperature, pressure, and velocity are needed to characterize high-speed flows and validate numerical simulations. To that end, this work demonstrates rapid, multi-parameter spectrally resolved planar laser-induced fluorescence (SR-PLIF) for spatially resolved, calibration-free measurements of these three key quantities using the gamma-bands of nitric oxide near 225.33 nm. The SR-PLIF technique was validated from 295-420 K and 3.48-20.4 kPa using a static gas cell and exhibits an average temperature and pressure error of 2% and 4%, respectively. The diagnostic was then used to study an underexpanded jet at rates up to 1 kHz and a spatial resolution of 220µm, with results showing favorable agreement with numerical simulations.
