Abstract
Disclosed herein is a nozzle for a combustor that burns fuel containing hydrogen. The nozzle comprised of a cylindrical tube is configured for introduction of a first fluid (for example, compressed air) and a second fluid (for example, hydrogen or a fuel containing hydrogen). Along an inner surface of the nozzle, one or more fluid vortex generators are disposed. As compressed air flows over the one or more fluid vortex generators, the compressed air swirls inside the nozzle resulting in a turbulent flow of the compressed air. As fuel is then introduced into the nozzle, the fuel encounters the swirling or turbulent flow of compressed air, and the introduced fuel is thoroughly mixed with the compressed air so that the fuel/air mixture will be combusted in a uniform manner. The nozzle may be included in a combustor of a gas turbine engine.
