Abstract
Official abstract text for this publication.
A method for producing substantially dendritic snow includes: a) supplying a flow of humid air ( 1 ) and a flow of cold air ( 9 ) into a substantially closed space ( 15, 16, 17 ) to mix the two air flows and create an atmosphere oversaturated with water within the space; b) forming ice crystals and allowing snowflakes to grow from the oversaturated atmosphere, keeping the ice crystals and growing snowflakes floating within the space and allowing them to grow over a predetermined period of time sufficiently long to obtain snowflakes having a predefined size, the floating condition being achieved by moving the ice crystals and growing snowflakes, on average, along a substantially helical trajectory by the air flow, which results in the snowflakes being distributed according to their size along the substantially helical trajectory; and c) thereafter releasing the predefined size snowflakes via a release opening ( 7 ) of the space by a carrier air flow ( 3 ).
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for producing substantially dendritic snow, comprising the following steps: a) supplying a flow of humid air and a flow of cold air into a substantially closed space in order to mix the two air flows therein and to form an atmosphere supersaturated with water within the substantially closed space; b) forming ice crystals including ice crystal nuclei and allowing snowflakes to grow from the supersaturated atmosphere depositing onto surfaces o…
