Based on the principle of hydraulics,an effective equipment of hydrodynamic cavitation is designed and built in this paper.The orifice plates with various geometry size were used as hydrodynamic cavitation generator to study the relation ship between many factor,such as,inlet pressure,discharge,flow speed in orifice,and the cavitation number.Analysis of water flow cavitation status for the experimental unit,this device can produce cavitation phenomenon.The methylene blue and spectrophotometer method can capture the free radicals generated succe...
