Project Title:

Hydroxyl Flow Tagging Velocimetry and Laser-Induced Raman Scattering for Measurement of Combustion Flows

Professor Robert W. Pitz

Brief Description of Project:

Advanced laser diagnostics are being developed for measurement of velocity and gas species concentrations in combustion. In this research, both hydroxyl tagging velocimetry (HTV) and Raman scattering will be further developed for application to a variety of flames including supersonic combustion. In HTV, water vapor is dissociated by a UV laser (193 nm) to form 11x11 grids of hydroxyl molecules in air and hot gases to determine velocity by time-of-flight displacement of the grid. In Raman scattering, the spectrum of light scattered from molecules is measured to determine gas composition and temperature in flames. These methods will be further developed for application to laboratory flames and propulsion test facility flows.

Nature of Supervision:

The student will work under the supervision of Robert Pitz with the assistance of graduate student, Shengteng Hu.

A Brief Research Plan (period is for 10 weeks):

The student would work with Professor Pitz and a graduate student on a specific project related to hydroxyl tagging velocimetry or Raman scattering. The research will include laboratory work and analysis.
