Abstract

We investigate the effects of rotation on spherical diffusion flames with emphasis on varying Lewis numbers on both the fuel and oxidizer sides. The study is motivated by recent theoretical development on the effects of rotation on droplet- or burner-generated flames. The experiments were devised not only to verify the theoretical predictions, but also extend or supplement the theories to study the flame response at high angular velocities where the perturbation theory no longer applies. The experiments were conducted using the 2.2 second drop tower at GRC. The flames were generated by injecting either the fuel or the oxidizer mixtures through a bronze porous burner to a controlled ambient which also comprises either an oxidizer or fuel mixture. As the theory predicted, the flame strengthened either at the pole or the equator as the Lewis numbers of the ambient and burner mixtures were varied.
