1. A method for atomizing a material, comprising the steps of:

  • providing a stream of a material to be atomized flowing in a first direction;

    injecting into the stream an atomizer gas in a direction generally across said first direction; and

    moving the stream through a progressively enlarging annulus having an interior surface so curved that the stream will flow along the contour of said interior surface without reverse eddies and without substantial turbulence;

    said injecting and moving steps being performed in such a manner as to cause the stream, the injected atomizer gas and said interior surface to cooperate to cause the stream to expand into a broader stream of atomized material.
