Applications of “snowind” engineering – climatic wind tunnel methods

Philippe Delpech,

Thomas Thiis


Transport and deviation of snow by wind induce many constraints on buildings, vehicles and industrial systems. A selection of questions from snow-wind engineering are presented in the paper. The experimental method that was undertaken to investigate these questions makes use of a large climatic wind tunnel, partly designed to address snow engineering problems at full scale: snow penetration in buildings, into ventilation systems of buildings and vehicles and snow or ice accretions on structures.
