Patent ID: 8464538

Claim:
A trapped vortex combustor, comprising: a trapped vortex cavity comprising a first surface and a second surface; a plurality of fluidic mixers disposed circumferentially along the first surface and the second surface of the trapped vortex cavity, wherein at least one fluidic mixer comprises: a first open end receiving a first fluid stream; a coanda profile in the proximity of the first open end; a fuel plenum to discharge a fuel stream over the coanda profile, wherein the coanda profile is configured to enable attachment of the fuel stream to the coanda profile to form a boundary layer of the fuel stream and, to entrain the incoming first fluid stream to the boundary layer of the fuel stream to form a mixture of the first fluid stream and the fuel stream; and a second open end for receiving the mixture of the first fluid stream and the fuel stream and discharging the mixture of the first fluid stream and the fuel stream in the trapped vortex cavity.
