Abstract
A bleed valve for a gas turbine engine, the valve comprises a diffuser having a plurality of holes through which a bleed fluid flows and into a fluid stream. The diffuser is characterized in that at least some of the holes are at least partially tangentially angled relative to the bleed fluid flow through the valve so that the bleed air forms a vortex to enhance mixing with the fluid stream.
