Fluid mechanics: liquid drop splash phenomenon |
Hi all
Does anyone know the correct physics term for the crown shape
phenomenon that occurs when a drop of liquid splashes? A friend of min
at UC Santa Cruz did his thesis on the topic in the early 1990s ('91 o
'92). He taught me the name, but I do not remember now and cannot fin
it anywhere
You can see high speed photography of a milk drop splash by Harol
Edgerton (MIT) at
-- http://web.mit.edu/Edgerton/www/HighSpeed.htm
There is recent research in this area. "Lei Xu, Wendy Zhang and Sidne
Nagel at the University of Chicago MRSEC have unearthed a spectacula
result: removing the ambient gas completely suppresses the splash
(See http://mrsec.uchicago.edu/research/nuggets/splash/). However, the
refer to it as a splash as well
I haven't been able to find a copy of any of the following to see i
they have the term listed
A.M. Worthington's A Study of Splashe
Macmillan, NY 1963 (1908
Harlow, F. H. and Shannon, J. P., "Computer's Analysis Capture
Delicate Crown of a Splashing Drop," Dateline in Science 2, No. 2
(December 15, 1967)
Harlow, F. H. and Shannon, J. P., "Distortion of a Splashing Liqui
Drop," Science 157, No. 3788, 547 (1967)
Harlow, F. H. and Shannon, J. P., "The Splash of a Liquid Drop," J
Appl. Phys. 38, 3855 (1967).
Thanks for your help

Yes. "Surface tension".

Seems simply to be called a 'crown':
Experimental investigation of splash and crown formation during single
drop impact on wetted surfaces
R. Rioboo, C. Bauthier, J. Conti, M. Voue´, J. De Coninck
Experiments in Fluids 35 (2003) 648–652
http://www.springerlink.com/content/m2uqanwvw5tuxtwh/fulltext.pdf
The dimensionless numbers that govern crown formation are the Weber and
Ohnesorge numbers. The distance between mini-jets is given by the
interfacial energy.
