Finite element analysis of the static flow in an ultrasonic air pump.

Abstract (in Japanese) (See Japanese page) 
(in English) An ultrasonic air pump utilizing acoustic streaming is discussed and its accurate simulation method using finite element analysis (FEA) is suggested in this paper. The pump induces air streaming in a thin air layer between a bending transducer and a reflector by exciting an intense sound field. The absolute sound pressure and the streaming velocity in the air layer is calculated being based on full-fluid dynamics through FEA, and the results are compared with experimental ones in the sound pressure and the flow velocity. As a result, the sound pressure was calculated in the derivation of the error of 5.9 %, and the measurement and analysis results for the streaming distribution meet in a good accuracy.
