The issue of cavitation number value in studies of water treatment by hydrodynamic cavitation
Ultrasonics Sonochemistry, 2017 Within the last years there has been a substantial increase in reports of utilization of hydrodynamic cavitation in various applications. It has came to our attention that many times the results are poorly repeatable with the main reason being that the researchers put significant emphasis on the value of the cavitation number when describing the ...
