Abstract: A turbine-compressor assembly includes a turbine-compressor device fluidly coupled with a heat source, a compressor, and a turbine via plural valves. A power device is coupled with the turbine-compressor device via a shaft. A controller can control operation of the plural valves to control the movement of fluids within the assembly to selectively switch between the turbine-compressor device operating in one of plural operating modes. In a first mode of operation, the turbine-compressor device can generate electrical power and direct the electrical power to the power device to control an amount of power provided to or extracted from the shaft by the power device. In a second mode of operation, the turbine-compressor device can receive electrical power from the power device to consumer the electrical power.

Abstract: A rotary assembly is provided that may be operably connected to an engine. The rotary assembly may include a rotary device comprising a turbine wheel, a shaft connected to the turbine wheel, and a case that houses the shaft and the turbine wheel. The turbine wheel may receive exhaust gas from the engine which causes rotation of the turbine wheel and the shaft. The case may include an interior surface that defines a hollow volume in which the turbine wheel and the shaft are located. The case has a radial thickness extending from the interior surface to an exterior surface of the case. The case may include a lattice structure integrated within the radial thickness of the case. The lattice structure may include a repeating three-dimensional array of frame segments connected to one another at junctions and defining interstitial spaces between the frame segments.

Abstract: A core body includes a structure having a plurality of connected unit cells. At least one unit cell has one or more sidewalls that are curved and define a portion of an inner passageway within and through the unit cell. The one or more sidewalls define multiple orifices and include a cone disposed between at least some of the orifices. A dimple is defined along an outer surface of the unit cell at the cone. The outer surface at least partially defines an outer passageway that is sealed from the inner passageway by the one or more sidewalls. The one or more sidewalls are configured to transport one or more of thermal energy from a first fluid or a component of the first fluid flowing in the inner passageway to a second fluid flowing in the outer passageway without the first fluid mixing with the second fluid.

Abstract: A turbocharger device includes a case having a turbine portion and a bearing portion connected to and extending from the turbine portion. The turbine portion defines a cavity that houses a turbine wheel and receives exhaust gas that rotates the turbine wheel. The bearing portion houses a shaft connected to the turbine wheel.

The lattice structure engages a turbine back wall that is located between the turbine portion and the bearing portion. The lattice structure defines interstitial spaces between the frame segments.

Abstract: A heat transfer apparatus includes an outer shell, an internal core body, and a flexible diaphragm extending from the core body to an interior surface of the outer shell. The shell includes a first inlet that receives a first fluid, a second inlet that receives a second fluid, a first outlet through which the first fluid exits the shell, and a second outlet through which the second fluid exits the shell. The core body forms first interior passageways that fluidly couple the first inlet with the first outlet and second interior passageways that fluidly couple the second inlet with the second outlet. The flexible diaphragm forms a flexible transition between each of the first inlet and the second inlet of the shell and the core body, and forms a seal that prevents the first fluid in the first interior passageways from flowing into the second interior passageways.
