摘要： A system for variably resisting flow of a fluid composition can include a flow passage and a set of one or more branch passages which intersect the flow passage, whereby a proportion of the fluid composition diverted from the passage to the set of branch passages varies based on at least one of a) viscosity of the fluid composition, and b) velocity of the fluid composition in the flow passage. Another variable flow resistance system can include a flow path selection device that selects which of multiple flow paths a majority of fluid flows through from the device, based on a ratio of desired fluid to undesired fluid in the fluid composition. Yet another variable flow resistance system can include a flow chamber, with a majority of the fluid composition entering the chamber in a direction which changes based on a ratio of desired fluid to undesired fluid in the fluid composition.

摘要： A fountain (50) comprises a supply of water under pressure, a primary fluidic diverter (10) having an input (12) for said supply, and first and second outputs (16a, b) diverging from said input. Two control ports (20a, b) are provided with control flow to direct input flow to one or other of the two outputs that lead to the two inputs of a vortex amplifier (40). This comprises a vortex chamber (54), a radial port (50), a vortex inducing port (60) and an axial output port (58). One (16a) of the diverter outputs is connected to the vortex inducing port, the other (16b) to the radial port, so that supply to said axial output port is modulated by formation of a vortex in the chamber when flow is to the vortex inducing port. The axial port leads to a nozzle whereby a vortex spray or axial jet is produced, depending on which diverter output (16a, b) is active.

摘要： A choke assembly comprises an inlet for a multiphase fluid stream, the stream comprising a first relatively heavy fluid phase and a second relatively light fluid phase; a first fluid outlet; a choke element disposed between the inlet and the first fluid outlet operable to control the flow of fluid between the inlet and the first fluid outlet; a separation chamber disposed to provide separation of phases in the fluid stream upstream of the choke element; and a second outlet for removing fluid from the separation cavity. The choke assembly is of particular use in the control of fluid streams produced from a subterranean well, in particular oil and gas produced from a subsea well.

摘要： A fluid flow control valve, especially for severe service, e.g. gas and oil power application, comprises a plurality of vortex chambers (9) through each of which fluid flows in substantially vortex fashion between an inlet channel (8) and a pair of opposed outlets (10, 11). Fluid enters each vortex chamber (9) from its associated inlet channel (8) in a substantially tangential direction wherein it splits into two flowpaths, each having both radial and axial components, leading to respective ones of the outlets (10, 11). The dual vortex outlet arrangement serves to further reduce the noise and erosion problems associated with severe service valves.

摘要： A system for conveying fluid through a conduit that creates a strong laminar flow of the material surrounded by a boundary layer flow of the same or a different flowable material, such that long transport distances through dramatic elevation and directional changes can be achieved. Some embodiments of the system include a blower assembly, an inlet conduit, an outlet conduit and a mixing chamber, wherein the mixing chamber includes an outer barrel, an inner barrel and an accelerating chamber. Gas is supplied to the system by the blower assembly and mixed with particulate material. The gas/material mixture is transported through the mixing chamber into the accelerating chamber and through the outlet conduit. In other embodiments, the particulate material is mixed with the gas in the accelerating chamber. Other embodiments of the system include only the mixing chamber, where a flow of at least one flowable material in the form of high or low pressure gas, liquid, and/or particulates suspended within the gas or liquid enters either laterally or axially, forms boundary layer and laminar flows, and exits through the accelerating chamber.

摘要： A fuel injector (2) including a combustion air flow conduit, a fuel inlet (2.4) and means to mix the air and fuel flowing therethrough (2.2, 2.3, 2.6), additionally comprising fluidic control means (2.7) including at least one control port (3.4, 3.5, 3.6, 3.7), such that flow of control air through said control port allows variation in the degree of flow resistance to which combustion air is subjected. For example, control air flowing through the control port may impart swirl to the combustion air flow from the inlet, thereby subjecting the combustion air flow to increased resistance. Alternatively a fluidic diverter (2.7) may selectively divert the main flow to either the first or second sub-conduits (2.2, 2.3), each sub-conduit subjecting combustion air to different degrees of flow resistance.

摘要： A system for separating a liquid and a gas comprises a separation vessel (30) with an inlet (28) for the gas/liquid mixture. Outlets (40, 42) for the fluids are disposed at different heights in the vessel. The outlets are controlled by turn-up vortex amplifiers (fluidic valves - TuVAs) comprising a supply port (40, 42), a control port (36, 38) and an outlet port (48, 50). The control port is supplied from the vessel at a level intermediate the outlets, so that a change in level of the interface between the gas and liquid about said intermediate level results in a change of flow in said control port, thereby altering resistance to flow through the valve.
