Pulsating water jets represent one of the ways to intensify effects of waterjetting technology on materials. In the first part of the paper, phenomena occurring during the impact of a drop of a liquid on a solid surface and reasons for their use leading to the generation of pulsating water jets are briefly described. In the next part, the concept of hydrodynamic nozzle for generating of pulsating water jets is briefly mentioned. The final part of the paper deals with the comparison of the erosive effects of continuous and pulsating jets generated by the acoustic generator and the hydrodynamic nozzle. Presented results proved superior performance of the pulsating jet generated by the acoustic generator. The hydrodynamic nozzle exhibits also great potential for significant improvement of water jetting performance.
