ABSTRACT:
A cyclone structure is provided for use in controlling the flow of two fluid streams to create a localized inward radial flow. The structure includes a chamber having a side wall disposed concentrically about a longitudinal axis and having first and second transverse end walls attached to respective ends of the side wall. A discharge tube is mounted in the first end wall concentrically about this axis and projects into the chamber. First and second inlets are provided adjacent the respective end walls and means is provided to move fluid under pressure into these inlets and into the chamber. The fluid enters the chamber in two distinct fluid paths moving vortically about the axis in the same direction of rotation, and the respective energy flow rates of fluid in these paths are comparable. The paths are generally vortical within the chamber and progress axially towards one another before combining where they meet to create the localized inward radial flow. Subsequently, the fluid leaves the radial flow and moves axially towards and out through the discharge tube. A method of providing the radial flow is also described.
