Abstract
High volume concentrated magneto-rheological (MR) fluids () is applied in many industrial fields. In the presented paper, a distance weighted chain-based model for predicting field-induced rheological behavior of high volume concentrated MR fluids is proposed. Simulated by Monte Carlo program, two important parameters: distance coefficient and adjustment coefficient β are introduced to quantify the contribution of micro structure in MR suspension, which considered as the most significant difference between new model and the alternative: standard isolated chain model. For testifying the validity of distance weighted model, four sets of, including three synthetic hydrocarbon oil-based () and a water-based self-prepared () samples’ rheological experimental and reported shear stress data are employed or prepared. The comparison of experimental data and theoretical values calculated by two models shows that in general, gain insight of neighboring chain interaction in model of rheological behavior seems indispensable. Implication of this model include that coefficient and β are the potential option for obtaining correct estimation of in highly volume concentrated magnetorheological fluids.
