  • Fluid Flow Control Device
    Publication number: 20100313982
    Abstract: A fluid flow control device that controls a flow of fluid within the flow control device has a flow path to convey the fluid. A cross-sectional area of the flow path varies along the flow path. At least a portion of the length of the fluid flow control device includes an active surface capable of influencing the fluid flow through the flow path to cause vortical motion of the fluid within the fluid pathway.

  • Swirl Inducer
    Publication number: 20090308472
    Abstract: A swirl inducer or mixer for location within a tube or duct. The swirl inducer may extend within the tube or duct and has an active surface over which a fluid flows to induce a swirling vortical flow within the fluid. The swirl inducer induces vortical flow in the tube or duct, which conforms with the path of least resistance and minimizes the amount of energy that is applied to the fluid to cause it to flow through the tube or duct and that causes the greatest, most rapid mixing of fluids passing through the tube or duct.
