摘要： The invention concerns a device for compressing gas using thermal energy. In a subsonic embodiment the heat gas passes through a convergent pipe C1 where it is provided with operating velocity, a convergent pipe C2 where it is simultaneously maintained at high speed and cooled by evaporation of liquid sprayed by nozzles R with adjustable position distributed in C2 . In a supersonic embodiment, the gas reaches sonic velocity at the throat of C2 and supersonic velocity in a divergent DG , then compressed in a convergent CG1 and simultaneously cooled by evaporation of sprayed liquid. In both embodiments, the gas is finally compressed in a subsonic divergent DG1 . Pipes with variable geometry enable to modify the cross-sections of the throats of the device. The device is essentially designed for thermoelectric power stations

摘要： A fluid mover (1) includes a hollow body (2) provided with a straight-through passage (3) of substantially constant cross section with an inlet end (4) an outlet end (5) for the entry and discharge respectively of a working fluid. A nozzle (16) substantially circumscribes and opens into the passage (3) intermediate the inlet (4) and outlet (5) ends. An inlet (10) communicates with the nozzle (16) for the introduction of a transport fluid and a mixing chamber (3A) is formed within the passage (3) downstream of the nozzle (16). The nozzle internal geometry and the bore profile immediately upstream of the nozzle exit are disposed and configured to optimise the energy transfer between the transport fluid and working fluid. In use, through the introduction of transport fluid, the working fluid or fluids are atomised to form a dispersed vapour/droplet flow regime with locally supersonic flow conditions within a pseudo-vena contracta, resulting in the creation of a supersonic condensation shock wave (17) within the downstream mixing chamber (3A) by the condensation of the transport fluid. Methods of moving and processing fluids using the fluid mover are also disclosed.

摘要： An aperture (5) connects a first chamber (1) with a second chamber (2), and is surrounded by an annular nozzle (7) formed by inner and outer walls (6, 8), which connects the first chamber (1) with a third chamber (3). A supersonic annular gas jet (9) is ejected by the annular nozzle (7) into the first chamber (1), creating a Venturi pumping action at the core of the jet in the vicinity of the aperture (5). The second chamber (2) may thus be maintained at a substantially lower pressure than the first chamber (1). Inner wall (6) and outer wall (8) may be relatively movable for varying gas flow, and the first chamber (1) may include baffles or skimmers to modify gas flow, e.g., to create a high density molecular beam. An electron or ion beam (4) may be transferred from the second chamber (2) to the first chamber (1), e.g., as part of an environmental scanning electron microscope.

摘要： A process is disclosed for operating a jet pump with an ejection nozzle that ejects an entrainment medium, in particular steam, at an ultrasonic speed, for mixing it with a gaseous load medium. In order to eliminate the azimuthal symmetry of the whirling structure of the entrainment medium in the mixing area located downstream of the outlet of the nozzle, the circumferential length of the entrainment jet is increased by giving to its cross-section a form other than circular. According to the continuity principle, the cross sectional area beginning in the ejection direction with a circular cross-section corresponds, in the ultrasonic part of the jet, to the circular cross-sectional area of the entrainment medium in conventional ultrasonic nozzles. Also disclosed is a jet pump, in particular a steam jet pump, with an ejection nozzle that expands from its neck to its end and that is surrounded by a coaxial mixing chamber to which a tapering diffuser part is connected. This jet pump for carrying out the process described in the first claim is characterised in that the cross-section of the expanding part (13) of the ejection nozzle (10) is formed by the neck (12) having a circular cross-section (Ak) with a corresponding circumferential length (LK), said neck (12) being a part of the ultrasonic part downstream of the jet. When the cross-sectional area (A) is given, the circumferential length (Lx) is larger than that obtained with the circular form. At least three projecting beads (18) that extend in the direction of the jet are shaped in the envelope (19) of the ejection nozzle.
