TWO STREAM TANGENTIAL ENTRY NOZZLE

摘要

A tangential air entry fuel nozzle has a combustor inlet port to permit air and fuel to exit into a combustor. The port includes a convergent surface, a divergent su rface, and a cylindrical surface extending therebetween. The convergent surface extends a f irst distance along the longitudinal axis of the nozzle, the cylindrical surface exte nds a second distance along the axis, and the second distance is at least 5% of the first dis tance.
