  • Publication number: 20060124187
    Abstract: A helical formation for a conduit (1). The helical formation includes an elongate member (4) defining at least a portion of a helix, the elongate member (4) comprising an inwardly extending portion (6, 7). The inwardly extending portion (6, 7) extends along the length of the elongate member (4) and extends inwardly from the internal side walls of the conduit (1) for a distance equal to between 10% and 80% of the distance (r) from the longitudinal axis (3) of the conduit (1) to an internal side wall (2).

  • Publication number: 20060047334
    Abstract: A Method of Determining the Helix Angle of a Helical Formation for a Conduit. A method of determing the helix angle of a helical formation (4) within a conduit (1). The method includes specifying the internal dimensions of the conduit (1) and an intended fluid mass flow through the conduit (1). The helix angle is determined from the pressure drop and the turbulent kinetic energy for a conduit (1) having the specified internal dimensions and intended fluid mass flow.

  • Publication number: 20050165289
    Abstract: A method of assessing the effect of a conduit section (11) on flow characteristics of a first fluid in a first conduit system (1). A first fluid is caused to flow through the first conduit system (1). A transverse flow parameter of the first fluid in the first conduit system (1) downstream of the conduit section (11) is detected. At least one transverse flow characteristic of the first fluid is determined from the detected transverse flow parameter. The effect of the conduit section (11) is then assessed from the determined flow characteristics.

  • Publication number: 20050061380
    Abstract: A helical formation (2) for a conduit (1). The helical formation (2) comprises an elongate member defining at least a portion of a helix, the elongate member comprising two inwardly extending portions (6, 7). The inwardly extending portions (6, 7) are spaced from each other and extend along the length of the elongate member in side-by-side relationship.
