Abstract	Submitted for the DFD07 Meeting of The American Physical Society Viscous Drop Impact on a Dry Smooth Surface: Spreading and Splashing CACEY STEVENS, Southern University and A&M College, and James Franck Institute, University of Chicago, NATHAN KEIM, WENDY ZHANG, SIDNEY NAGEL, James Franck Institute, U. of Chicago — The splashing of a liquid drop on a smooth dry surface is dependent on the pressure of the surrounding air.1 Recent findings suggest, however, that the pressure-dependent splashing of a viscous drop is by a different mechanism than that for an inviscid one. For example, unlike an inviscid liquid, a viscous liquid splashes only after the drop has spread to nearly its maximum extent.2 Here we report on experiments with viscous silicone oil (10–1000 cSt) that examine the parameters affecting the spreading of a viscous drop upon impact, and the role of the surrounding gas in splashing. Of particular note is the strong effect of viscosity on spreading rate and behavior. 1L. Xu et al., Phys.Rev. Lett.94, 184505 (2005) 2L. Xu, Phys. Rev.
