The paper deals with the setting of the CFD model with a magnetorheological fluid and its influence on the results. The rheological behaviour of MR fluid under magnetic field was described by the Bingham constitutive equation. Two magnetorheological valves based on parallel plate simplification are presented. The influence of the number of elements and setting BIAS factor across the gap, entrance and exit losses and velocity profile development on the pressure drop is carried out. The results indicate that for accurate computation the minimum number of elements across the gap is 30 and a suitable BIAS factor is 1.5 or more. The influence of entrance and exit losses on pressure drop in the gap is more significant for conventional hydraulic oil than for MR fluid. These results were used in slit-flow rheometer developing
