Abstract [en]

This report documents the adaptation of a two dimensional two phase Navier-Stokes solver to axisymmetric problems. The changes from Cartesian to cylindrical coordinates are thoroughly described with finite difference methods for the heat equation, Poisson equation, single and two phase Navier-Stokes equations.The jump conditions at interfaces are modified to accommodate these changes for the two phase Navier-Stokes equations. The changes to the solver are done step by step, and every change is verified through intermediate test cases with analytical solutions to limit the possible sources of errors. Finally all stepwise changes are joined together to form an axisymmetric two phase Navier-Stokes solver. Results are presented for a resting bubble, and for both viscous and inviscid oscillating elliptic bubbles.
