A vortex amplifier, both of the diode and triode types, is a device that is applicable in many hydraulic and gaseous flow situations where flow modulation is required. This report studies the functional, structural and performance characteristic of common type diodic and triodic vortex amplifiers.
Typically, the supply flow of fluids enter it along the peripheral perimeters of a central cylinder to be drawn radially and differentially in terms of fluid kinetic energies to the central parts of the cylinder from where the fluid exits axially along the exit throat or diffuser (King, 1987). The mechanism that creates the differentials between the kinetic energies of the entering fluid and the exiting one is the core functional part of the device. The efficiency of the device depends on its ability to destroy the kinetic energies of the entering flows by generating a vortex. that also helps create the required kinetic energies of the exiting flows (King, 1987).
Typically, a control flow also enters the peripheral parts of the central cylinder to meet the supply flow tangentially, modulating its kinematic characteristics and inducing it to move to the central parts of the cylinder in a free vortex (King, 1987). The kinetic energies of the control flow increases that of the supply flow and the total flow ends up in the central parts of the cylinder in a free vortex. The turbulent interactions at the downstream parts of the exit throat ultimately destroys parts of the total kinetic energies of the flow and only the exiting flow is allowed out with only the required kinematic characteristics (King, 1987). ...
