Thermocapillary Flow in an Annular Two-Layer Liquid System
Keywords:Thermocapillary flow, Interface deformation, Lattice Boltzmann method.
By means of a hybrid lattice Boltzmann method, thermocapillary flow, driven by the surface tension owing to a horizontal temperature gradient along the interface in immiscible two-layer liquid system, is simulated numerically. The dynamic behavior of the interface is captured by using phase-field theory. The dependence of flow and interface deformation on the density ratio, Capillary number and aspect ratio, is investigated.
