  • Laboratory study of frazil ice accumulation under wave conditions 

    De La Rosa, Sara; Maus, Sønke (Copernicus Publications, 2012-02-09)
    Ice growth in turbulent seawater is often accompanied by the accumulation of frazil ice crystals at its surface, forming a grease ice layer. The thickness and volume fraction of this ice layer play an important role in ...
