    Abstract: A counterflow heat exchanger includes a first fluid inlet, a first fluid outlet fluidly coupled to the first fluid inlet via a core section, a second fluid inlet, and a second fluid outlet fluidly coupled to the second fluid inlet via the core section. The core section includes a plurality of first fluid passages configured to convey the first fluid flow from the first fluid inlet toward the first fluid outlet, and a plurality of second fluid passages configured to convey the second fluid flow from the second fluid inlet toward the second fluid outlet such that the first fluid flow exchanges thermal energy with the second fluid flow at the core section. One or more drains are operably connected to the plurality of first fluid passages configured to remove condensation from an interior of the first fluid passages prior to the condensation reaching the first fluid outlet.

    Abstract: A hybrid powerplant can include a fuel cell cycle system configured to generate a first power using a fuel and an oxidizer. The powerplant can also include a supercritical carbon dioxide (sCO2) cycle system operatively connected to the fuel cell cycle to receive heat from the fuel cell cycle to cause the sCO2 cycle system to generate a second power.

    Abstract: A method of fabricating an oscillating heat pipe includes building the oscillating heat pipe with a layer-by-layer additive manufacturing process such that the oscillating heat pipe includes a body of solid material, an array of channels, an evaporator portion, and a condenser portion. The array of channels are disposed in the body and define a continuous loop through which a fluid flows. The array of channels is formed by cavities in the body as the body is formed with layer-by-layer additive manufacturing. An inner surface of a channel includes a flow directing feature that is configured to promote a first direction of flow and that is configured to provide resistance against a second direction of flow that is opposite the first direction of flow.

    Abstract: A heat exchanger includes a first additively manufactured layer including axial fins extending in a first direction and transverse fins extending in a second direction transverse to the first direction, the first layer defining a flow path in the first direction. The heat exchanger also includes a second additively manufactured layer including axial fins extending in the second and transverse fins extending in the first direction, the second layer defining a second flow path in the second direction.

    Abstract: A heat exchanger assembly embodiment includes a plurality of laminated ceramic tape layers having at least one hole surrounded by at least one tape remainder portion. The plurality of layers is arranged in a build direction defined parallel to a counter-flow plane. Each laminated ceramic tape layer is stacked and sintered to define a ceramic core section integrally formed with a first ceramic manifold and a second ceramic manifold. The ceramic core section of the assembly includes a plurality of spaced apart counter-flow plates stacked along a stacking direction normal to the counter-flow plane and the build direction, defining a plurality of flow passages parallel to the counter-flow plane. Each flow passage is in communication with the first manifold and the second manifold. A plurality of counter-flow fins is disposed in at least one of the plurality of flow passages, between adjacent ones of the plurality of counter-flow plates.

    Abstract: A ram air fan inlet assembly for cabin air compressor (CAC) motor cooling flow enhancement includes a gas path defined by a ram air duct and a fan section, a CAC motor cooling return duct having an outlet provided through a wall of the ram air duct, and a centerbody body disposed in the ram air duct. The fan section is disposed immediately downstream and abutting the ram air duct. The ram air duct and fan section share a common axis. The centerbody is disposed about the common axis and configured to reduce of volume of the gas flow path in the ram air duct. The centerbody and the outlet axially overlap.
