Effect of Water Flow Rate on Operating Frequency and Power During Acoustic Chamber Tuning

Original language description

Tuning of an ultrasonic system for pulsating water jet technology for efficient power transmission is discussed in this paper. The efficiency of the ultrasonic transducer depends upon the stiffness of the water interacting with it. The stiffness of water depends upon the inlet volume flow rate inside the acoustic chamber controlled by supply pump pressure and diameter of the nozzle. The interactional effect of varying water stiffness and the sonotrode efficiency can be adjusted by varying the acoustic chamber length. It changes the space required by the standing waves inside the chamber to achieve optimal amplitude near the nozzle exit. Therefore, supply pressure of 20, 30 and 40 MPa, nozzle diameter of 0.3-1 mm and chamber length from 0 to 22 mm were used in this study to observe the change in the operating frequency and output power of the sonotrode. The results showed that at lower flow rate (<3.0 l/min), the optimal chamber length depends upon both supply pressure and nozzle diameter. However, for flow rate above 3.06 1/min, the achieved resonance frequency depends solely on volume flow rate. The optimal chamber lengths observed are 20 and 21 mm for flow rate ranging from 3.06 to 5.43 l/min and 5.88 to 12.01 l/min, respectively. These results can be used as quick settings of the system in the resonance regime for future experiments.
