Computational and experimental study of laminar premixed and nonpremixed flames

摘要

The coupling of adaptive numerical methods with large memory parallel/vector computers has produced an extremely powerful tool with which to probe flame structure. In this presentation we investigate both numerically and experimentally axisymmetric laminar flames. Specifically, we illustrate the application of coflow flames to problems in soot formation and oxidation and propellant modeling. Computationally, we solve the governing conservation equations of mass, momentum, species balance and energy with detailed transport and finite rate chemistry submodels. Experimentally, we apply spontaneous Raman spectroscopy and laser induced fluorescence to generate profiles of the temperature, the major and some minor species of the flame.
