Abstract
A combustor nozzle includes a downstream surface having an axial centerline. A plurality of passages through the downstream surface provide fluid communication through the downstream surface, and a downstream section of each passage has at least one of a frusto-conical or frusto-spherical shape. A method for modifying a combustor nozzle includes machining a downstream side of a body to remove a recast surface in a plurality of passages that provide fluid communication through the body. The method may further include machining a downstream section in each passage to form at least one of a frusto-conical or frusto-spherical surface in each passage proximate to the downstream side of the body.
