The procedure of nozzle design, numerical flow modelling, quality testing and functionality of the nozzle are presented. Well defined modulated jets were observed up to 1.5 MPa of input water pressure with an oscillation frequency of 88 kHz. Erosion characteristics of the modulated jets were investigated on soft gelatine samples. Three basic jet orientations were tested with respect to the eroded samples and to the trajectory of the nozzle movement. The erosion process of the MWJ was monitored using high-speed shadowgraph techniques. Then, the erosion depth was determined by image analysis methods. The test results show that the best erosion effect was obtained using the nozzle with 45° orientation with respect to the traverse direction.
