Abstract

This paper describes the development of a piezoelectric flextensional transducer, which aims to effectively degrade the TCE contained in aqueous solution. In order to adjust the 1st flextensional resonant frequency and output displacement of the flextensional transducer, the effect of the geometrical variations on performance was analyzed using the finite element analysis (FEM). The results indicated that the effect of external shell's thickness and curvature were most significant, and experimental fabrication and characterization of a transducer was performed to confirm the results. To prove the capacity to degrade the TCE contained in aqueous solution, 50 and 100 ppm of TCE were prepared in sealed chamber, and investigated the removal rate of TCE through the time and initial concentration.
