Testing of frequencies generated in water by submerged high-energy liquid jet

pages 88 - +4p., full text

Utilization of water jets is rather well known for cutting and removing of materials in air. Nevertheless, utilization of water jets for similar works under the water level causes health problems to operators. Testing of high-energy liquid jet outflow to the pressure vessel indicates that there is a very high probability of generation of quite strong ultrasonic wave field. This contribution is aimed at measurements realized in the laboratory of the high-energy liquid jet at the VŠB Technical University Ostrava. The experiments were performed for pressures simulating submersion from the water level up to the depths 160 meters below it.
