LASER-INDUCED SURFACE-TENSION-DRIVEN FLOWS IN LIQUIDS

摘要

High-intensity, short-pulse laser radiation incident on the free surface of an absorbing dielectric liquid results in heating that can alter the liquid surface tension, causing Marangoni convection. This flow can dominate the transport of thermal energy in the liquid. In this work, both a scaling analysis and a full numerical simulation of the governing equations are performed. A thermal mechanism is proposed as the driving force for these flows.
