관 내 세정을 위한 초음파 음장 연구

초록

This paper presents some results of research for applying ultrasonic cleaning to an interior wall of cylindrical pipe. As the cleaning is achieved better for higher sound pressure, ultrasonic sound field in a cylindrical container is considered. The paper identifies nonuniform sound field established by the radiation of a cylindrical transducer driven at resonant frequency. Numerical analysis predicts the sound pressure distribution, and experiment verifies the trend of analysis results. Experiment observes the cleaning effect, and this paper suggests the possibility of using a cylindrical ultrasonic cleaning device.
