Abstract
An atomizer comprising a liquid inlet, a gas inlet arranged to receive a pressurized flow of gas, a liquid flowpath extending from the liquid inlet to a liquid stream outlet, and a curved gas flowpath extending from the gas inlet to a location adjacent the liquid stream outlet and including a supersonic flow region adjacent the liquid stream outlet, whereby supersonic gas flow adjacent the liquid stream outlet produces a shock wave which impinges on a liquid stream passing out through the liquid stream outlet for atomizing the liquid stream.
Claims15
An atomizer comprising:
- a liquid inlet;
- a gas inlet arranged to receive a pressurized flow of gas;
- a liquid flowpath extending from the liquid inlet to a liquid stream outlet;
- a generally helical gas flowpath extending from the gas inlet to a location adjacent the liquid stream outlet and including a supersonic flow region adjacent the liquid stream outlet and an elongate, generally cylindrical, atomizing flowpath region downstream of the supersonic flow region and extending to an atomizer outlet,
- whereby supersonic gas flow adjacent the liquid stream outlet produces a shock wave at least partially reflected from a cylindrical wall of said elongate flowpath, which impinges obliquely on a liquid stream passing out through the liquid stream outlet for atomizing the liquid stream in the atomizing flowpath region.

A method for atomizing comprising the steps of:
- providing a pressurized flow of gas to a gas inlet and through a generally helical gas flowpath;
- providing a liquid flowpath extending from a liquid inlet to a liquid stream outlet;
- causing the pressurized flow of gas to undergo supersonic flow at a supersonic flow region adjacent the liquid stream outlet, thereby to produce a shock wave, at least partially reflected from a cylindrical wall of said elongate flowpath, which impinges obliquely on a liquid stream at an elongate, generally cylindrical, atomizing flowpath region downstream of the supersonic flow region extending to an atomizer outlet for atomizing the liquid stream in the atomizing flowpath region.
