Attenuator’s Volume Influence on High Pressure’s Pulsations in a Jet Cutting Unitd with pulsations attenuator. The influence of the attenuator’s volume upon the pressure’s pulsations before the nozzle is further on studied for a unit provided with pressure multiplier. The attenuator’s minimum volume can be established on the basis of these results, so that the pressure pulsation does not exceed a maximum imposed value.作者: 侵害 時間: 2025-3-22 04:25 作者: sebaceous-gland 時間: 2025-3-22 05:48 作者: 六個才偏離 時間: 2025-3-22 12:11 作者: 含糊其辭 時間: 2025-3-22 15:08 作者: probate 時間: 2025-3-22 18:12
Investigation of the Pure Waterjet-Workpiece Interactionnism. The excitation is produced by the microdroplets and small vapor/air cavities, nature of the impinging waterjet. It is also demonstrated experimentally that making the workpiece resonate to the ultrasonic wave to increase the oscillating stress substantially enhances the cutting rate.作者: JOT 時間: 2025-3-23 01:15
Measurement of Particle and Drop Velocities in a Mixed Abrasive Water Jet Using a Forward-Scatter LD describes a method used for abrasive water jet velocity measurements which uses a forward-scatter LDV system. Using the forward-scatter technique makes it possible to utilize a thin, low power laser to produce a small probe volume. Results are presented for velocity measurements obtained over a range of operating conditions and mixing tube sizes.作者: 推延 時間: 2025-3-23 01:53

A Study of the Practicality of Cavitating Water Jets years, their use is not as widespread as, for example, that of abrasive-entrained water jets. Good performance of cavitating water jets has mainly been documented under submerged conditions, where it is limited, for a given set of operating conditions, to very short standoff distances.
