Paper Abstract

High temperature water vapor detection in hypersonic exhaust has been the subject of ongoing research in a collaboration between MetroLaser and Vanderbilt University's Department of Mechanical Engineering. In this paper we examine some of the temperature sensitivity issues surrounding water vapor diagnostics based on two-photon fluorescence measurements. We present work which shows a large temperature sensitivity for the two-photon excited fluorescence features for H2O in a hydrogen and air flat flame burner. The spectra are modeled for various temperatures, results are experimentally verified, and recommendations are made.
