Patent number: 8683812Abstract: In an air mixing arrangement wherein a primary fluid is introduced through an opening in a wall to be mixed with a secondary fluid flowing along the wall surface, the opening is airfoil shaped with its leading edge being orientated at an attack angle with respect to the secondary fluid flow stream so as to thereby enhance the penetration and dispersion of the primary fluid stream into the secondary fluid stream. The airfoil shaped opening is selectively positioned such that its angle of attack provides the desired lift to optimize the mixing of the two streams for the particular application. In one embodiment, a collar is provided around the opening to prevent the secondary fluid from contacting the surface of the wall during certain conditions of operation. Multiple openings maybe used such as the combination of a larger airfoil shaped opening with a smaller airfoil shaped opened positioned downstream thereof, or a round shaped opening placed upstream of an airfoil shaped opening.Type: GrantFiled: April 27, 2011Date of Patent: April 1, 2014Assignee: United Technologies CorporationInventors: Fabio R. Bertolotti, David S. Liscinsky, Vincent C. Nardone, Michael K. Sahm, Bernd R. Noack, Daniel R. Sabatino

Patent number: 6360763Abstract: A diffuser (7) has a step (12) in the surface (9) just upstream of a point where boundary layer separation might occur. An acoustic jet (22) has a nozzle (17) immediately downstream of the step (12); the acoustic jet is driven (25) by a plurality of frequencies, one or more of which are subharmonics of another of them, and having different phases.Type: GrantFiled: April 20, 2001Date of Patent: March 26, 2002Assignee: United Technologies CorporationInventors: Satish Narayanan, Bernd R.
