Abstract
A fluid mover includes a hollow body with a straight-through passage of substantially constant cross-section with an inlet end an outlet end for the entry and discharge respectively of a working fluid. A nozzle substantially circumscribes and opens into the passage intermediate the inlet and outlet ends. An inlet communicates with the nozzle for the introduction of a transport fluid, and a mixing chamber is formed within the passage downstream of the nozzle. The nozzle internal geometry and the bore profile upstream of the nozzle exit optimize the energy transfer between the transport fluid and working fluid. Working fluids are atomized to form a dispersed vapor/droplet flow with locally supersonic conditions within a pseudo-vena contracta, resulting in the creation of a supersonic condensation shock wave within the downstream mixing chamber by the condensation of the transport fluid. Methods of moving and processing fluids using the fluid mover are also disclosed.
