  • Publication number: 20210088285
    Abstract: A heat exchanger including a plurality of tubes, a header, and a plurality of flow voids. The plurality of tubes extends in a first direction through which a first fluid is configured to flow. Each of the plurality of tubes have waves that repeat at regular intervals along the first flow direction and are spaced from one another vertically and laterally in the second direction. The header extends in the first direction and is attached to each of the plurality of tubes. The header is configured to convey the first fluid to each of the plurality of tubes. The plurality of flow voids are formed between the plurality of tubes. The plurality of flow voids extend in a second direction through which a second fluid is configured to flow such that the second fluid is in thermal contact with the plurality of tubes.

  • Publication number: 20200166293
    Abstract: A heat exchanger is disclosed herein that includes three walls that are each shaped in a wave pattern with the waves that extend in both a first lateral direction and a second lateral direction. A second wall is adjacent to and in contact with a first wall with the waves of the second wall being offset from the waves of the first wall by one-half wavelength in the first direction. The third wall is adjacent to and in contact with the second wall with the waves of the third wall being offset from the waves to the second wall by one-half wavelength in the second direction. The first wall and second wall form a first plurality of flow paths extending in the second direction, and the second wall and the third wall for a second plurality of flow paths extending in the first direction.

  • Patent number: 10627111
    Abstract: A fuel mixer for mixing a fuel and an oxidizer prior to detonation in a rotating detonation engine includes a combustion channel configured to transport a final mixture of the fuel and the oxidizer for combustion. The fuel mixer also includes a mixture channel positioned upstream from the combustion channel and configured to transport a first mixture having at least some of the fuel and at least some of the oxidizer. The fuel mixer also includes a secondary outlet positioned upstream from the combustion channel and configured to output a supplemental mixture of the fuel and the oxidizer that includes at least one of the fuel or the oxidizer such that the first mixture and the supplemental mixture combine in the combustion channel to form the final mixture.

  • Patent number: 10436110
    Abstract: A rotating detonation engine includes an annulus that defines a volume in which a mixture of an oxidizer and a fuel detonate in a rotating fashion, the volume defining a downstream outlet through which detonation exhaust flows. The rotating detonation engine further includes a wave arrestor positioned upstream from a location of detonation and configured to reduce a magnitude of a pressure wave traveling upstream from the location of detonation.

  • Publication number: 20180274788
    Abstract: A rotating detonation engine includes an annulus that defines a volume having a detonation region which is configured for a mixture of an oxidizer and a fuel to detonate in a rotating fashion, the volume defining a downstream outlet through which detonation exhaust flows. The rotating detonation engine further includes an oxidizer outlet configured to output the oxidizer into the volume. The rotating detonation engine further includes a fuel outlet configured to output the fuel into the volume such that the oxidizer and the fuel are initially insufficiently mixed to facilitate combustion. The rotating detonation engine further includes an obstacle positioned upstream from the detonation region and configured to mix the fuel and the oxidizer that are directed upstream in response to a passing detonation.

  • Publication number: 20180274787
    Abstract: A rotating detonation engine includes an annulus having a first wall, a second wall, and a volume having a detonation region in which a mixture of an oxidizer and a fuel detonate in a rotating fashion to create a pressure wave and detonation exhaust, the volume defining a downstream outlet through which detonation exhaust flows. The engine further includes an oxidizer outlet to output oxidizer and a fuel outlet to output fuel into the volume. The engine further includes an obstacle positioned in the volume and extending for an obstacle distance between the first wall and the second wall that is at least twenty five percent of an annulus distance from the first wall to the second wall, the obstacle designed to reflect the pressure wave such that a reflection of the pressure wave travels downstream and reduces an amount of the detonation exhaust that travels upstream.
