Claim Text:
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 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 at injection locations defined in the member about a periphery of the flowpath at first and second locations along the elongate axis and into the flowpath, the injected second fluid being formed into jets at the first and second locations, the first fluid entraining the jets such that the injected second fluid flows through the flowpath and mixes with the first fluid, and the short axis having a sufficient dimension such that the jets remain spaced from a sidewall of the member.
