"The Plateau–Rayleigh instability, often just called the Rayleigh instability, explains why and how a falling stream of fluid breaks up into smaller packets with the same volume but less surface area. It is related to the Rayleigh–Taylor instability and is part of a greater branch of fluid dynamics concerned with fluid thread breakup. This fluid instability is exploited in the design of a particular type of ink jet technology whereby a jet of liquid is perturbed into a steady stream of droplets. " - Rayleigh jet breakup

TīmeklisPast experimental studies have indicated that the Rayleigh fission of a charged drop occurs via the formation of a jet followed by emission of progeny droplets. In order to understand this process, we model the evolution of a drop using an axisymmetric boundary element method in the viscous limit.
