• Acoustic cavitation was investigated in a microreactor containing micromachined pits. A 200 kHz transducer attached to the microreactor generated localized cavitation that originated from the micropits. Both sonoluminescence (SL) and sonochemiluminescence (SCL) were used for quantifying the caviation activity under different experimental conditions. At low power levels, the cavitation activity was limited to the pit region. At high power levels, cavitation streamers from the pits (for 2 and 3 pits setups) tend to approach each other that resulted in an increased cavitation activity in the region between the pits. Key results that will be discussed include (i) significant differences observed in SL and SCL activities under different experimental conditions and (ii) experimental proof for the transient nature of the cavitation bubbles, by measuring SL in propanol solutions.
