Patent number: 9255745Abstract: A heat exchanger has a fluid passage sharing a wall with a cooling fluid passage adjacent to the passage. The thermally conductive wall allows heat to be transferred from the fluid into the cooling fluid passage. The passage additionally has a set of at least one airfoil pin extending into the passage.Type: GrantFiled: January 5, 2009Date of Patent: February 9, 2016Assignee: Hamilton Sundstrand CorporationInventors: Fabio P. Bertolotti, Daniel R. Sabatino

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.

Publication number: 20080098894Abstract: A fuel delivery system includes a fuel stabilization unit that receives vibratory energy for mixing fuel within fuel passages to improve the removal of dissolved oxygen from an oxygen containing fuel. A vibration generator transmits vibratory energy into the fuel stabilization unit to induce mixing of fuel. Vibratory energy is directed into the fuel to create enhanced mixing by inducing large-scale secondary flow motions that circulates fuel from a center flow area toward an oxygen permeable surface to improve overall fuel deoxygenation as more of the fuel is placed in adjacent contact with the oxygen permeable membranes.Type: ApplicationFiled: November 1, 2006Publication date: May 1, 2008Inventors: Daniel R.
