  This paper presents a solver using the Level-Set method for incompressible
two phase flows with surface tension. A one fluid approach is adopted where
both phases share the same velocity and pressure field. The Level Set method
has been coupled with the Ghost Fluid Method. An efficient and pragmatic
solution is proposed to avoid interface displacement during the
reinitialization of the level-Set fields. A solver called LSFoam has been
implemented in the OpenFOAM framework with consistent Rhie & Chow
interpolation. This solver has been tested on several test cases covering
different scales and flow configurations: rising bubble test case,
Rayleigh-Taylor instability simulations, Ogee spillway flow, 3D dambreak
simulation with a square cylinder obstacle and KVLCC2 steady resistance
calculations. Overall results are in excellent agreement with reference data
and the present approach is very promising for moderate free surface
deformations.
