| Abstract |
磁性流体やMR流体といった磁気機能性流体を取り巻く環境を動的に変化させ, 磁気機能性流体の動的諸特性を明らかにすることを目的として, 超音波伝播特性に関する実験, 新しい衝撃緩衝器として, テーパー付きピストンを有する構造を提案し, その内部流れの解析および実験を, 遂行した。その結果, 非定常磁場下での様々な現象をある程度明らかにすることができた。
Magnetic fluids (MF) and magnetorheological fluids (MRF) are stable colloidal dispersion of small magnetic particles in a liquid carrier. When an external magnetic field is applied to an MF or MRF, some of the inner particles coagulate and form a clustering structure. In the present study,the following experiments were carried out : (1) Ultrasonic propagation velocity was measured and the change of ultrasonic propagation velocity was calculated. Based on the experiment results, the relation between the change of ultrasonic propagation velocity and magnetic field strength and frequency of AC magnetic field were discussed. (2) used Bingham plastic model was used to represent the dynamic behavior of MR fluid flow in a circular pipe under a magnetic field theoretically. The author carried out the flow experiment of MR fluid at a constant flow rate and compared experimental results and analytical results quantitatively.
