Acoustics of Periodic and Multiple Drop Impacts on a Water Surface
High-speed video filming of surface currents and synchronized acoustic measurements of the underwater sound signals of falling drops were performed...
-
Aerothermodynamics, Nonlinear Acoustics and the Meteorological Equations
The study of low-Mach-number flows occurs in the general context of asymptotic modelling of fluid flows, and in a recent book (Zeytounian 2004, Chap....
