The breakup processes of steady and pulsating jets are simulated using a threedimensional incompressible SPH method. Experiments are also carried out and the results are compared. It is shown that the pinch-off length of a liquid jet depends on the Reynolds number. It oscillates at the same frequency as the pulsating jet. It is shown that the SPH can simulate these characteristics, though the pinch-off length tends to be longer when the jet velocity periodically changes with time.
