In the framework of numerical study of multiphase flows, different front‐capturing methods are compared. Two different approaches dealing with the incompressibility constraint will be compared, too. Then, every technique is tested on several relevant test cases in order to make a comparison. The surface tension treatment is evaluated for each method and every front‐capturing method is tested on a case where interface deformations have something in common with turbulent behaviour. Finally, every method is studied through a phase inversion problem, which is an unsteady test case. Front‐capturing methods are tested on physical cases where Navier–Stokes and advection equations are coupled in a non‐linear way. Copyright © 2008 John Wiley & Sons, Ltd.
