Abstract:
A fuel injector arrangement for a combustion apparatus, comprising:at least one passage for the flow of fluid, said passage being of substantially annular cross-section, being defined by a radially inner wall and a radially outer wall and having an inlet region and an outlet region, said inlet region incorporating a plurality of vanes adapted to modify a flow pattern of a fluid entering said inlet region, such that fluid passing from the inlet region to the outlet region has a composite flow pattern having both an axial component and a component rotational about the longitudinal axis of the passage, each vane being provided with a root, a mid-region and a tip, each vane being contoured such that an existing axial flow of fluid entering said inlet region continues substantially unaffected at the root and tip but is partly converted into a rotational flow as it flows past the mid-region.
