Particle Accumulation Structures in Thermocapillary Convection of Liquid Bridge

Thermocapillary convection in a liquid bridge is induced by non-uniform surface tension distribution over the free surface owing to a temperature difference between two cylindrical rods sustaining the liquid bridge. The induced flow is usually visualized by using fine particles as tracers. Under certain flow conditions, the tracer particles were found to form particle accumulation structures (PAS). Four types of PAS were found in different flow...
