Abstract: A surface cooler includes a plate-like layer and a plurality of spaced-apart fins extending substantially perpendicular from an uppermost layer of the plate-like layer. The plurality of fins defining a plurality of air flow paths. The plurality of spaced-apart fins are configured to augment heat transfer of the surface cooler by increasing the turbulence levels of a fluid flowing through the airflow paths by promoting increased mixing with a resulting increase in the heat transfer coefficient of the surface cooler. A method of forming the surface cooler and an engine including the surface cooler.

Abstract: An assembly comprises a first cooling cavity disposed within one or more of a turbine assembly or a combustion chamber of an engine. The first cooling cavity directs cooling air within the one or more of the turbine assembly or the combustion chamber. The assembly comprises a second cooling cavity also disposed within the one or more of the turbine assembly or the combustion chamber. The second cooling cavity receives at least some of the cooling air from the first cooling cavity. A forward facing step nozzle forms a channel that fluidly couples the first cooling cavity with the second cooling cavity. The step nozzle includes steps having elongated first sides and narrow second sides. The elongated first sides of the steps protrude into the channel such that a cross-sectional area of the channel of the step nozzle at the steps is smaller than a cross-sectional area of the channel of the step nozzle outside of the steps.

Abstract: A surface cooler includes a conduit, a body having an external surface, and a plurality of fin members arranged in an array of fin members. The conduit defines an inlet, an outlet, and an internal flow path extending between the inlet and the outlet. The conduit is configured to channel a flow of fluid to be cooled from the inlet to said outlet. The conduit extends through the body. Each fin member of the array of fin members extends from the external surface of the body. Each fin member is fabricated from a thermally conductive resilient and pliable material.

Abstract: A method for reducing noise generated by a wind turbine includes measuring a reference temperature of the wind turbine. The method also includes regulating a trailing edge surface temperature of a trailing edge portion of a rotor blade attached to the wind turbine. In addition, the method includes measuring the trailing edge surface temperature. Further, the method includes regulating the trailing edge surface temperature to maintain a predetermined temperature differential between the reference temperature and the trailing edge surface temperature.

Abstract: A surface cooler includes a base component, a plurality of first fins, and a plurality of second fins. The base component has a first surface, a second surface, and a first thermally conductive material. The plurality of first fins extends substantially perpendicular from the first surface and each first fin is characterized by a first height and a first width. The plurality of second fins extends substantially perpendicular from the first surface and each second fin is characterized by a second height and a second width. One or more fins of the plurality of first fins are disposed between a pair of adjacent fins of the plurality of second fins and an average first height of the plurality of first fins is lower than an average second height of the plurality of second fins. The plurality of fins reduces air drag and augments heat transfer capacity of surface cooler.
