Velocity Field Bimodality in an Axisymmetric Diffusion Flame Combustor
Resumo
The unsteady flow characteristics prevailing in a simple axisymmetric combustor are described. Unexpected
bimodal velocity distributions are present in various regions of the flow, which are not captured in mathematical
models. Understanding and accurate modeling of such flow behavior is essential as it can significantly affect
the fuel/air mixing process, thus impacting combustion efficiency and emissions. A physical model is proposed
to explain the observed flow behavior.
