Flat jet fluid nozzles with fluted impingement surfaces
Abstract:
The invention is flat jet fluid nozzles having at least one fluid channel useful for making snow. The fluid channel is defined in part by opposed upper and lower fluted impingement surfaces leading to a slotted orifice. When tiny droplets of water are ejected from the slotted orifice into sufficiently cold atmosphere, they can rapidly freeze into snow.
