New Developments
in Unstable Interfacial Fluid Mixing
Interfacial fluid mixing induced by an external force (Rayleigh-Taylor
instability) or by a shock wave (Richtmyer-Meshkov instability) plays
an important role in science and engineering applications, such as supernova, DT
laser, and nuclear physics. These interfacial fluid mixings are highly unstable
and nonlinear. Recently, several important developments have occurred. The
speakers will present these new developments. They will discuss physical and
mathematical modeling, analytical theories, and numerical computations.
Quantitative agreement between the theoretical predictions and the results from
numerical simulations have been achieved.
