Originální abstrakt

This contribution describes results of measurement of magnetorheological fluid MRF-140CG by LORD Corporation. Results of this measurement are used as an inputs to the CFX model. MR fluid has been measured in special slit-flow rheometer at temperature range from 25 to 60 °C and at magnetic field of 0, 146, 280 a 368 kA/m. The flow curves were compiled with the respect of Bingham model of MR fluid Non-Newtonian behavior. Bingham model has two parameters – yield stress and Bingham (plastic) viscosity. Thanks to high precise measurement of pressure drop, the temperature dependence of yield stress is visible. All measured rheological properties were used as an input to the model describing MR fluid behavior in dependence on temperature and magnetic field.
