Abstract
A mixing device is comprised of a pair of nested flow separator conduits (202, 204) with convolutions (201, 206) on the outlet ends (203, 205) and means of adjusting the relative position of the convolutions on one of the outlet ends relative to the convolutions on the other outlet end. The relative movement of the convolutions (201, 206) provides a method to modulate the rate of mixing between flows passing through the flow separator conduits (202, 204). Exemplary embodiments of the invention include application of the mixing device as a furnace (20) and as a gas turbine combustor (150).
