From the results obtained in the study, the following conclusions can be made:The methylene blue and spectrophotometer method can capture the free radicals generated successfully. This is an effective way to measuring the free radicals quantitatively in cavitation, moreover it is easy to fulfill.The intensity of cavitation increases with reduction in the cavitation number. But the different mechanism of various enhancive processes (chemical and physical processes) results in different effect by cavitation number.The effect of operating parameters, such as inlet pressure, temperature and time on cavitation indicate that optimum operating conditions exist at the cavitation enhancive effect is maximum.It is important to optimize the structure of hydrodynamic cavitation reactor for achieving a desired effect. A reasonable geometric parameter can promote the enhancive effect for a fixed hydrodynamic condition.Ventilating appropriate gas to cavitating flow can increase cavitational intensity and hence promote the enhancive effect of hydrodynamic cavitation.
