Abstract

Use of LIF in two line thermometry TLT and of flash lamp absorption to examine high enthalpy flows is presented. The aim is to measure rotational and vibrational temperatures of nitric oxide NO in high temperature air in the Göttingen High Enthalpy Shock Tunnel HEG. Theory of NO (energy levels, spectroscopy, level populations), LIF and TLT are discussed. Results are given from a test cell to validate TLT with NO LIF as a quantitative technique. HEG results for rotational and vibrational temperatures in the free stream and around models are presented. Finally, flash lamp absorption results yielding these temperatures are given.
