Abstract
Official abstract text for this publication.
A combustion system premixer includes one or more streamwise vortex generators configured to passively redirect surrounding high velocity air into at least one of wake and vortex regions within a combustion system fuel nozzle in response to air passing through the premixer. The streamwise vortex generators operate to minimize turbulent flow structures, thus improving air/fuel mixing, and enhancing resistance to flame-holding and flash-back within the premixer.
First claim
Opening claim text (preview).
The invention claimed is: 1. A combustion system premixer comprising: one or more streamwise vortex generators configured to passively redirect surrounding high velocity air into at least one of wake and vortex regions within a combustion system fuel nozzle to reduce turbulent flow structures in response to the high velocity air passing therethrough; wherein the one or more streamwise vortex generators comprise at least one notch structure, at least one shaped groove, or at leas…
