Abstract (en)

[origin: EP1657509A1] The method involves reproducing snow development conditions in upper atmosphere to reproduce in situ the artificial snow in an open autonomous enclosed space freed from external climatic conditions. A unidimensional flow is created at a temperature independent of the external temperature. A static pressure is created independent of the atmospheric pressure. The flakes transported by a stable gas layer are evacuated from the flow. An independent claim is also included for an installation for making artificial snow.
