Abstract: In this study, the flow behaviour of Magneto-Rheological (MR) fluid through complex valve geometries is investigated using analytical, computational and experimental approaches. A two-dimensional MR valve model is constructed for computational simulation based on a unique MR device that has circular, radial and annular flow regions. When compared with analytical solutions, the results of the Computational Fluid Dynamics (CFD) model, which has taken into account minor losses of MR fluid flow in different valving areas, are in good agreement with those of experimental measurements. It has been shown that the Bingham CFD model works well for complex flow geometries in the two-dimensional domain and that the CFD method can be greatly beneficial in the design and development of MR devices for practical applications.

Keywords: MR fluids; magnetorheological fluid flow; complex valves; CFD; computational fluid dynamics; valve geometries; modelling; simulation.
