Exceptional atomization of liquids is achieved by combining shock wave formation and vortex generation in a gas stream. In a vortex generating device, a flow passage is aligned with a flow axis connected between a fluid inlet and a fluid outlet, and a plurality of tornado-like gas vortices are generated in the flow passage. In one embodiment, a restriction is formed in the fluid inlet, and a source of gas under sufficient pressure to cause sonic velocity at the restriction is connected to the inlet. In another embodiment, a restriction is formed in a downstream portion of a flow passage, and a pair of auxiliary flow passages connect an upstream portion of the flow passage to the restriction. In an embodiment, a fluid outlet has a concave semispherical surface opening into an ambient region. In another embodiment, a first annulus is formed in the flow passage by a rod, and a second annulus is formed in the flow passage by the rod and a reduction in cross-sectional area of the flow passage; a source of atomizing gas under pressure and a source of liquid under pressure to be atomized are both connected to the fluid inlet.
