Summary

In this paper we present a 2D Volume of Fluid two phase flow model with surface tension. The model is based on the incompressible Navier -Stokes equations, it uses implicit time stepping, unstructured grids and staggered finite volumes. A cubic spline interface interpolant which preserves the volume fraction distribution is introduced. Interface adaptive and/or interface aligned deformable grids are reconstructed in each time step with help of either a linear or spline interface approximation. Anomalous currents around bubbles are significantly reduced with help of cubic spline interpolants. The simulations of buoyant bubbles are compared with known theoretical, numerical and experimental results.
