Summary
A numerical method for two-dimensional unsteady free-surface flows including effects of surface-tension was developed to investigate the convection generated by vapour bubbles in nucleate boiling systems. This paper presents the incorporation of the free-surface conditions into the implicit segregated solution approach for the incompressible Navier-Stokes-equations. The finite-volume discretization is based on the physical contravariant velocity components in a staggered boundary-fitted grid. The results for non-steadily departing and rising bubbles compare well with experimental data from the high-speed cinematography.
