本研究では懸濁系の磁気粘弾性流体の流動特性と圧力特性について四要素モデルを用いて考察を行う．実験では，磁気粘弾性流体がオリフィスを流れる際の圧力損失について，スタートアップの圧力変化と磁場印加時の圧力の過渡的な挙動を測定した．また実験結果の検証として数値解析も行った．その結果，磁気粘弾性流体の流れは，ケルビン力，磁気スピンの作用，物性を決定づける4要素モデルによって数値的に表現されることを明らかにした． / The flow and pressure characteristics of magneto-viscoelastic fluids in suspension systems are discussed in this study using a four-element model. In the experiment, the pressure drop of the magneto-viscoelastic fluid flowing through the orifice was measured in terms of pressure change at startup and transient pressure behavior when a magnetic field is applied. Numerical analysis was also performed to verify the experimental results. The results show that the flow of a magneto-viscoelastic fluid can be numerically described by a four-element model that determines the Kelvin force, the action of magnetic spin, and physical properties. / 博士(工学) / Doctor of Philosophy in Engineering / 同志社大学 / Doshisha University
