Comprehensive numerical computations are made of Lid-Driven Cavity flow. Two layers of immiscible liquids are contained in the enclosure. Numerical solutions are acquired to the governing Navier-Stokes equations. No a priori assumptions are made on the shape and dynamical role of the interface. VOF method suggested by Hirt et al. was utilized after some modifications to prevent smoothing of free boundary occurs when a conventional scheme is used. Attention is directed to the effect of a parameters on the interface deformation and top drag force.
Explicit influences of the Froude number and of the viscosity ratio are scrutized. The global flow patterns are visualized, and friction coefficient along the top and bottom wall are plotted.
