摘要:
A three-dimensional printing process, a swirling device 102, and a thermal management process are disclosed. The three-dimensional printing process includes distributing a material to a selected region, selectively laser melting the material, and forming a swirling device from the material. The swirling device 102 is printed by selective laser melting. The thermal management process includes providing an article having a swirling device 102 printed by selective laser melting, and cooling a portion of the article by transporting air through the swirling device.
摘要:
The drainage system comprises a gully (18) having a circumferential side wall (38), an outlet (26) and a vortex brake (36) with a vortex chamber having a chamber wall (50, 52, 54) with a peripheral inlet opening and a central outlet opening, the vortex brake being arranged in the gully so that a flow path from the inside of the gully to the outlet (26) leads through the vortex brake (36), a drainpipe (28) being connected to the outlet (26). The vortex brake (36) is arranged in the gully so as to be non-demountable, and the vortex brake (36) is provided with a flushing access (72) having a hose connection (74).
摘要:
The present invention relates to piping (1) for use in industrial activities, where the piping (1) has a specific geometry. In particular, the piping (1) is formed as a low amplitude helix, which causes fluid flowing through the piping (1) to swirl. This swirl flow provides a large number of advantages. Particular applications where the piping (1) can be used include reactors for chemical and petrochemical applications.

Embodiments of the invention provide apparatuses and methods for depositing materials on substrates during vapor deposition processes, such as atomic layer deposition (ALD) . In one embodiment, a chamber contains a chamber lid (832) containing an expanding channel (834) formed within a thermally insulating material (838) either directly within the chamber lid or formed within a funnel liner attached thereon. The chamber further includes at least one conduit (841 a-d) coupled to a gas inlet within the expanding channel and positioned to provide a gas flow in a circular direction, such as a vortex, a helix or a spiral. The chamber may contain a retaining ring (819), an upper process liner (822), a lower process liner (824) or a slip valve liner (826) . Liners usually have a polished surface finish and contain a thermally insulating material such as fused quartz or ceramic. In an alternative embodiment, a deposition system contains a catalytic water vapor generator connected to an ALD chamber.

A fuel fill system includes a funnel (18, 70) having an inlet port (20) configured to receive a nozzle (22) from an external fuel source, a fuel filler tube (16) coupled to an outlet port (24) of the funnel (18, 70), and a vapor recirculation tube (30) coupled to the funnel. Fuel vapor entering the funnel (18, 70) from the vapor recirculation tube (30) is directed toward the outlet port (24) at a first angle less than 90° from a longitudinal axis (34) of the funnel (18, 70). The fuel vapor entering the funnel (18, 70) may also be directed at a second angle less than 90° from a line (50) tangent to an inner surface of the funnel (18, 70) at a point where fuel vapor enters the funnel. The second angle is in a plane perpendicular to the longitudinal axis (34) of the funnel (18, 70).
摘要:
A fluid pathway (36) provided with a flow controller (37) in at least a portion of its length wherein the flow controller (37) comprises an active surface capable of influencing the fluid flow (34) through the fluid pathway (36), the configuration of the active surface conforming to at least one logarithmic curve conforming to the Golden Section.
摘要:
According to the present invention there is provided fluidising apparatus comprising: a flow chamber 2 having a fluid inlet 4 and a fluid outlet 6; means 18 for establishing a swirling flow in a fluid passing out of the fluid outlet; and a transport outlet 30 for transporting fluidised material away from the flow chamber 2, the transport outlet 30 being situated externally of the flow chamber 2.
