“…The height (175 µm) and width (290 µm) of the serpentine microreactor were chosen to be considered a microfluidic channel (i.e. < 1000 µm) and they are within the range of reported microchannels in which cavitation has been observed (20–1000 µm height, 100–1000 µm width) [21] , [22] , [23] , [24] , [25] , [26] , [27] , [28] , [29] , [30] , [31] , [32] , [33] , [34] , [35] , [36] , [37] . For the channel length (7.0 cm), an intermediate value was chosen within reported values (1.2–28 cm).…”
