ABSTRACT:
A method and apparatus for forming ice crystals for seeding an air-water mixture in making snow comprising an aspirator in communication with a first chamber, a second chamber connected to the first chamber through a first mixing tube, and a second mixing tube leading from the second chamber to an outlet. Low pressure air is introduced to the second chamber, and high pressure water is supplied to the aspirator to provide a high speed jet of water for evacuating air from the first chamber and driving a mixture of air and water droplets along the first mixing tube and into the second chamber wherein the mixture is accelerated by the flow of low pressure air through the second chamber and along the second mixing tube. A reverse flow of the low pressure air in the first mixing tube interacts with the jet of water to form a homogeneous mixture of water droplets and air in the first mixing tube, and the mixture in combination with more of the low pressure air is introduced to the second mixing tube wherein it is mixed, atomized and cooled by accelerated expansion as it flows along the mixture tube to form ice crystals leaving the outlet.
