In this study, SPH (smoothed particle hydrodynamics) simulations have been performed on the jet break-up and impinging jet considering the effect of the surface tension. For the jet break-up simulations, the liquid pillar was broken into multiple droplets due to the surface instability caused by the surface tension, and the effect of the injection velocity corresponded well with experimental results. For the impinging jet simulations, the film thickness of the impinged liquid on the solid wall corresponded quantitatively well with experimental results especially for high Reynolds numbers. The effect of the surface tension on the film profile was almost negligible for the simulated range.
