- 論文の詳細を見る
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 streaming velocity in the air layer are calculated on the basis of full-fluid dynamics through FEA, and the calculation results are compared with experimental results for the sound pressure and flow velocity. As a result, the sound pressure is calculated in the derivation of the error of 5.9%, and the measurement and analysis results for the streaming distribution are in good agreement.
