Investigation of capillary wave formation on water streams with internally propagating ultrasound
Investigation of capillary wave formation on water streams with internally propagating ultrasound
The present work investigates the formation of capillary waves and subsequent breakup on 10 mm and 15 mm diameter water streams (measured at the nozzle exit) with ultrasound propagating at 135 kHz. Experimental observations of the stream breakup process with a high speed camera are reported. The input signal to the transducer was used to investigate the formation and growth of capillary waves. Lateral spraying of the water stream was observed prior to the formation of surface waves. Once the surface waves are formed, they grow in size leading to a necking zone. Necking can, if sufficiently large, lead to fragmentation of the stream into globules. The capillary wavelength, lateral spraying velocity and water stream breakup length are measured and presented in an attempt to understand the nature of the breakup process.

Abstract
The present work investigates the formation of capillary waves and subsequent breakup on 10 mm and 15 mm diameter water streams (measured at the nozzle exit) with ultrasound propagating at 135 kHz. Experimental observations of the stream breakup process with a high speed camera are reported. The input signal to the transducer was used to investigate the formation and growth of capillary waves. Lateral spraying of the water stream was observed prior to the formation of surface waves. Once the surface waves are formed, they grow in size leading to a necking zone. Necking can, if sufficiently large, lead to fragmentation of the stream into globules. The capillary wavelength, lateral spraying velocity and water stream breakup length are measured and presented in an attempt to understand the nature of the breakup process.
