Jcw. Rogers et Wg. Szymczak, COMPUTATIONS OF VIOLENT SURFACE MOTIONS - COMPARISONS WITH THEORY ANDEXPERIMENT, Philosophical transactions-Royal Society of London. Physical sciences and engineering, 355(1724), 1997, pp. 649-663
A numerical implementation of a generalized hydrodynamics has been use
d to compute a number of violent surface motions (characterized by the
collision of different portions of the free surface). For some of the
se motions, singular aspects of the surface evolution may be analysed
theoretically. Comparisons of the output of the calculations with theo
retical predictions are made for these cases. In a second test of the
predictions of the generalized hydrodynamics, the evolution of a plume
generated by underwater explosions is compared with a computed plume
history. An important diagnostic tool for studying violent surface mot
ions has been analysis of the sum of the kinetic and internal energies
of the flow. Accordingly, we include some results of an investigation
into mechanisms for energy dissipation, as well as a description of s
ome relations between energy loss and modes of cavity collapse.
