Experimental investigation of splash and crown formation during single drop impact on wetted surfaces (2003, background): “The break-up processes also show fundamental differences, as shown in results and observations from, for example, Mundo et al. (1995), Cossali et al. (1997), Yarin and Weiss (1995), Roisman and Tropea (2002) and Rioboo et al. (2001).”
The splash/non-splash boundary upon a dry surface and thin fluid film (2006, background): “This is consistent with the origin of splashing being a kinematic discontinuity and ensuing instability phenomena within the outward directed fluid (Allen 1975; Yarin and Weiss 1995; Rieber and Frohn 1999; Bussman et al. 2000; Kim et al. 2000; Trujillo and Lee 2001; Roisman and Tropea, 2002; Josse”
Review of mass and momentum interactions during drop impact on a liquid film (2016, methodology): “Crown height The model by Roisman and Tropea [96] shows that nondimensional crown height, H⁄ = H/ddrop, increases appreciably with increasing h⁄.”
The role of time in single drop splash on thin film (2004, methodology): “The geometrical parameters during the crown expansion have been defined in Yarin and Weiss (1995) and Roisman and Tropea (2002) , taking the initial film thickness as a constant length to scale the thickness of the spreading lamella, which is not a good approximation for very thin films (with a dim”
