✦ Synopsis

In this communication a computational model for incompressible ¯ow with the eect of surface tension is brie¯y described. The formulation for calculating surface tension is developed based on a variational approach. It is assumed that the variations in surface energy, which may contribute to the ¯uid motion, should not change the total energy. A formulation expressed in the colour function is then derived. The colour function is computed by an advection scheme that predicts the ®rst order spatial derivatives of the colour function as well. The ®rst order derivative computed directly from the advection equation is then used to ®nd the surface tension related quantities.
