  • Publication number: 20150285044
    Abstract: A method for flow manipulation within a porous volume. Steps include inducing a sequence of fluid flows between fluid sources and fluid sinks disposed at at least three spaced locations in or around a porous volume, the fluid flows being induced by providing fluid at one or more of the sources and extracting fluid at one or more of the sinks. Successive fluid flows in the sequence are induced at predetermined times and oriented in different directional orientations between different sources and sinks, the successive fluid flows define different flow volumes which at least partially intersect one another, and the successive fluid flows are selected to induce cross-directional flows to mix one or more fluids in the porous volume.

  • Patent number: 9062541
    Abstract: Described embodiments relate to methods, systems and infrastructure for flow manipulation within a porous volume. Some embodiments relate to a method of subsurface flow manipulation, comprising: providing fluid at a first subsurface location adjacent to or in a subsurface volume through which the fluid is to pass; providing first suction at a second subsurface location adjacent to or in the subsurface volume to extract fluid from the subsurface volume, the second subsurface location being located across at least part of the subsurface volume from the first subsurface location; providing fluid at a third subsurface location spaced from the first subsurface location and adjacent to or in the subsurface volume; and providing second suction at the first, second or a fourth subsurface location adjacent to the subsurface volume to extract fluid from the subsurface volume.

  • Patent number: 7690833
    Abstract: A heat exchanger is disclosed which includes an elongate fluid duct having a series of openings and an outer sleeve disposed outside and extending along the duct to cover the openings. A drive motor is provided for imparting relative motion between the duct and the sleeve so that the sleeve moves across the openings in the peripheral wall of the duct. A temperature control device which may include an outer jacket arranged about the sleeve to define a chamber for receiving a heat exchange fluid, an electric heating element for supplying current to the outer sleeve or duct to heat the outer sleeve or duct, a series of burners for heating the outer surface of the sleeve, or a heating element incorporated in one of the duct and sleeve.

  • Patent number: 7448500
    Abstract: A method of separating particulate material of differing size or density including the steps of: tumbling the particulate material to produce continuous or discrete avalanches (19) in the surface of the particulate material to move particles of smaller size (14) or higher density (22) towards the centre of the particulate material and particles of larger size (16) or lower density (24) radially outward from the centre of the particulate material; and extracting particles at selected radial locations (8, 10). A device for separating particulate material of differing size or density is also provided.

  • Patent number: 7121714
    Abstract: A fluid mixer including an inner fluid flow (11) duct having a cylindrical wall (14) provided with the window openings (13) and an outer tubular sleeve (12) disposed outside and extending along the duct (11) to cover the openings (13). Fluids to be mixed are admitted to one end of duct (11) through an inlet (25) and the mixture flows out through outlet (32). Duct (11) is statically mounted in pedestals (15) fixed to a base platform (17). Sleeve (12) is mounted for rotation in further pedestals (16) and driven by motor (23) and drive belt (22) to rotate concentrically about duct (11) such that parts of the sleeve move across the window openings (13) to create viscous drag on fluid flowing through the duct and transverse flows of fluid in the regions of the openings to promote mixing.
