摘要： The flow through the core of a hybrid pulse detonation combustion system is passed through a compressor and then separated into a primary flow, that passes directly to the combustor, and a bypass flow, which is routed to a portion of the system to be used to cool components of the system. The bypass flow is routed to a nozzle of the pulse detonation combustor. The flow is then passed back into the primary flow through the core downstream of where it was extracted.

The endwall extends between the radially inner surface and the radially outer surface. A plurality of vanes are coupled to the endwall. The vanes extend outwardly from the endwall. Adjacent vanes form a pair and are spaced a circumferential distance apart such that a flow channel is defined between each pair of circumferentially-adjacent vanes. The flow channel extends generally radially between an inlet opening and an outlet opening. A first supersonic compression ramp is coupled to the endwall. The first supersonic compression ramp is positioned within the flow channel to facilitate forming at least one compression wave within the flow channel.

摘要： A heat exchange assembly for treating carbon dioxide (CO2) is described. The heat exchange assembly includes a housing that includes an inlet, an outlet, and an inner surface that defines a cavity extending between the inlet and the outlet. The housing is configured to receive solid CO2 through the inlet. At least one heat exchange tube extends through the housing. The heat exchange tube is oriented to contact solid CO2 to facilitate transferring heat from solid CO2 to a heat exchanger fluid being channeled through the heat exchange tube to facilitate converting at least a portion of solid CO2 into liquid CO2. The heat exchange assembly is configured to recover a refrigeration value from the solid CO2 and transfer at least a portion of the recovered refrigeration value to a flue gas.
