Magneto-rheological fluid (MR fluid) is one of the functional fluids which responds to the magnetic field and exhibits a semi-rigid behavior even under a small magnetic field strength. Then, MR fluid plugging performance by aggregation of magnetized particles in MRF is recently expected to be one of the most promising applications to medical or safety devices, such as blood flow control or steam shut-down valve. In this study, dynamic response of MRF plugging in pressure mode with fluid/wall interactions was experimentally investigated, considering the effects of applied magnetic flux density, piston head velocity, wall surface structure and elasticity of biological tube. The final objective of this study is to provide the fundamental data for the novel applications of MR plugging performance to medical or safety devices for flow control.
