Abstract
Official abstract text for this publication.
A fuel injector is provided and includes a member defining a flowpath through which a first fluid flows, the flowpath having a cross-section with transverse elongate and short axes, a head defining a plenum storing a supply of a second fluid and a system fluidly coupled to the flowpath and the plenum to inject the second fluid from the plenum and into the flowpath at first and second locations along the elongate axis. The injected second fluid is formed into jets at the first and second locations, the first fluid entrains the jets such that the injected second fluid flows through the flowpath and mixes with the first fluid, and the short axis has a sufficient dimension such that the jets remain spaced from a sidewall of the member.
First claim
Opening claim text (preview).
The invention claimed is: 1. A fuel injector, comprising: a member defining a flowpath through which a first fluid flows, the flowpath having a cross-section with transverse elongate and short axes, wherein the member is disposed in a space between a liner and a flow sleeve disposed about the liner through which a liner flow travels such that the elongate and short axes are disposed at complementary angles that are each between 0 and 90 degrees with respect to the liner flow; a…
