Numerical simulation of lance-jet impinging on a liquid free surface was carried out and validated against the experimental data of Ueno et al. [Tetsu-to-Hagané, 101 (2015), 74]. Computational domain was separated to lance domain and water-bath domain. Lance domain was solved as single phase of compressible gas and the result was used to inlet boundary condition of water-bath domain by volume of fluid method (VOF) solver. Large eddy simulation (LES) was used and both solver are a part of OpenFOAM, open source CFD toolkit. The time average of depth and diameter of cavity was almost consistent with the experiment. The standard deviation was 10-20% of the time average and slightly larger than that of the experiment. Simulation showed that sloshing of water surface might enhance the spitting phenomena.
