LATTICE BOLTZMANN SIMULATIONS OF DROP DEFORMATION AND BREAKUP IN SHEAR FLOWS

A lattice Boltzmann method for multicomponent immiscible fluids is applied to simulations of drop deformation and breakup in shear flows for various capillary numbers and viscosity ratios at three different Revnolds numbers, Re = 0.2, 1, 10. The effect of the Reynolds number on drop deformation and breakup in shear flows is investigated. It is found that the drop is easier to deform and to be ruptured as the Reynolds number increases.
