The dynamics of a cavitation bubble under acoustic field and an electric field is studied by regarding liquid as a working medium. The effects of the dimensionless frequency and strength of acoustic field and electric field on cavitation bubble dynamical behaviors by Rayleigh-Plesset equation are numerically investigated. The results show that when acoustic field and electric field are combined, chaos area range of cavitation bubble motion is larger than that when only acoustic field or single electric field exists. This is of significance not only for further research of acoustic cavitation but also for enhancing and improving the cavitation degration of organic pollutant technology.
