Webb5 okt. 2005 · Therein, splashing upon a dry surface is reasonably described by √Ca > 0.35, reflecting the competing roles of surface tension and viscosity. Splashing upon a thin fluid film, as described by √We > 20, is governed by fluid density and surface tension, but is rather independent of viscosity. Webb10 feb. 1999 · Three cases are chosen to typify the splash interaction with the free surface of the collapsing cavity: (i) surface reconnection around the liquid jet; (ii) splash impact at the base of the liquid jet; (iii) thin film splash. Hydrodynamic pressures generated following splash impact are found to be much greater than those produced by the jet impact.
