Article Synopsis
- A novel experimental method using pulsed ultrasound measures the size distribution of bubbles involved in sonoluminescence and sonochemistry.
- Increasing the pulse on-time can lead to larger, coalesced bubbles, while minimizing this duration or adding sodium dodecyl sulfate helps measure smaller, active cavitation bubbles.
- The study identifies an average bubble radius of 2.9-3.0 µm in Ar-saturated water at a frequency of 362 kHz, discussing the influence of acoustic power and standing waves on bubble behavior.
Purging of solutions to enhance sonochemical reactions is a common practice. A fundamental study combining sonoluminescence spectroscopy and sonochemical activity is adopted to study the effects of continuous Ar gas flow in the solution and of the position of the gas inlet tube on high-frequency sonolysis of aqueous solutions. It has been observed that neither sonochemical activity nor sonoluminescence intensity is controlled by the gas solubility only.
