Abstract
A comparison between two algorithms is conducted with a collocated mesh for incompressible Navier-Stokes equations with the surface tension as a source term. Two different techniques are employed for calculation of the pressure gradient and the continuous surface tension. For an initial static bubble without gravity, the spurious currents and pressure distribution are shown to illustrate the differences between the algorithms for treatment of the source term and between the techniques for calculation of the pressure gradient and the surface tension.
