Abstract: The present disclosure involves designs for a fluid channel assembly that allow for a high entrainment ratio while also sustaining a high fluid mass flow rate through the assembly. The fluid channel assembly includes a first fluid passage and a second fluid passage, where the first and second fluid passages are arranged such that fluid from the second fluid passage is entrained in fluid from the first fluid passage. Fluid passes through at least a portion of the first fluid passage in a form of a plurality of first fluid streams.

Abstract: An apparatus for generating power includes a heated fluid reservoir including a heated fluid, a back-pressure control channel, an energy extractor coupled to the heated fluid reservoir and the back-pressure control channel, and a pressure ejector coupled to the back-pressure control channel. The back-pressure control channel includes a fluid mobilization device configured to circulate an internal fluid and to form a low-pressure region within the back-pressure control channel. The energy extractor includes an energy extraction rotor. The low-pressure region in the back-pressure control channel causes the heated fluid from the heated fluid reservoir to be entrained through the energy extractor forming an entrained fluid. The energy extraction rotor is configured to extract power from the entrained fluid. The pressure ejector is configured to transmit the entrained fluid to an exhaust reservoir.
