Abstract: A heat exchanger is provided that can include furcating unit cells coupled with each other. Each of the unit cells can be elongated along an axis and include a sidewall that defines annular ring openings on opposite ends of the unit cell along the axis. The sidewall also can define undulating annular rings between the annular ring openings and axially separated from each other along the axis. The sidewall can further define angled openings into the unit cell both above and below each of the undulating annular rings. At least a first opening of the annular ring openings and the angled openings can be configured to be an inlet to receive a first fluid into the unit cell and at least a second opening of the annular ring openings and the angled openings configured to be an outlet through which the first fluid exits the unit cell.

Abstract: A heat exchanger for an aircraft includes an inlet plenum housing defining an inlet plenum configured to receive a fluid and an outlet plenum housing defining an outlet plenum configured to discharge the fluid. Furthermore, the heat exchanger includes a core configured to heat or cool a first portion of the fluid, with the core defining a plurality of fluid passages extending from the inlet plenum to the outlet plenum. Moreover, the heat exchanger includes a passive bypass defining a passive bypass flow path fluidly coupled to and extending between the inlet plenum and the outlet plenum. As such, the passive bypass flow path is in parallel with at least a portion of the core such that a second portion of the fluid bypasses at least a portion of the core and flows continuously and unobstructed through the passive bypass flow path to the outlet plenum.

Abstract: An additively manufactured heat exchanger and a method of manufacturing the same are provided. The heat exchanger includes a plurality of walls spaced apart to define a plurality of fluid passageways and a plurality of flow turbulators extending between two adjacent walls through the fluid passageways. The walls and flow turbulators define one or more internal fluid passageways in thermal communication with the plurality of fluid passageways which receive a flow of auxiliary heat exchange fluid for enhancing the heat transfer efficiency of the heat exchanger.

Abstract: The present disclosure generally relates to methods for radiographic and computed tomography (CT) inspection of workpieces having increasingly complicated internal geometry. The disclosed methods are capable of distributing a contrast agent within the detailed internal geometry of, for example, an AM workpiece or precision cast turbine blade, followed by complete removal of the contrast agent and all residues thereof after inspection.
