Induced Swirl In A Combustion Premixer
The photo shows a steady CFD solution of the atmospheric combustion "buzz" rig in the Hopkinson Lab. The "buzz" rig contains a scale model of the Rolls-Royce Plc RB211-DLE swirl-stabilised flameholder. The photo shows the atan (y-velocity/z-velocity) within the upstream section of the swirler. The swirl vanes (wedge shapes) and fuel injectors (circular shapes) have been removed during rendering. This image has had the original grey rendered background removed, and a black/blue gradient background added instead.
