Reactive autophobic spreading of drops

[摘要] We use a lubrication theory approximation to formulate a model for the reactive spreading of drops that deposit an autophobic, monolayer of surfactant on a surface. The model consists of a Poisson equation on a moving domain with boundary conditions that depend on the history of the domain motion. We develop a numerical algorithm for-solving the model, using the immersed interface method and the level-set method. Numerical solutions for traveling drops are qualitatively similar to experimental observations of reactive autophobic spreading. (C) 2002 Elsevier Science (USA).
