Sonochemistry and Bubble Dynamics in Small Channels
* Presenting author
Sonochemistry in small channels requires active cavitation bubbles in confined environments. Here we investigate the chemical activity of sonicated aqueous solutions in millichannels and look for correlations with observed bubble dynamics. The indicative chemical reactions like sonochemiluminescence (luminol) rely on OH radical formation. Parameter variations include channel dimension, ultrasonic frequency and power, and the liquid flow speed. Final aim is a better understanding and optimization of millichannel flow reactors for process intensification by non-classical means.
