Research is aimed predominantly at the high-speed water jet
disintegration of rock and rock-like materials. Main areas of
interest can be defined as intensification of water jet effects,
research on abrasive materials for abrasive water jet cutting,
and development of unconventional methods of shaping of rock and
rock-like materials. Intensification of water jet effects by
pulsing the jet includes research on process of excitation and
propagation of high-frequency pressure pulsations in liquid and
their utilization for generation of high-speed pulsating water
jets. Dynamic behaviour of pulsating water jet is studied both
theoretically using CFD methods and experimentally using jet
visualization, direct measurement of dynamic pressure and impact
force of pulsating jet. Interaction of pulsating jet and
material is studied using optical methods and image analysis to
define processes occurring during the interaction as well as
effects of the pulsating jet on newly created surface. Topic
