The paper focuses on numerical analysis of temperature field into a magneto-rheological break. The magneto-rheological fluid is used for a brake operated at different speeds. The magneto-rheological brake application was developed due to the magnetic control and fast response. The two dimensional axi-symmetric computational domain corresponds to the experimental magneto-rheological break. The numerical simulations have been performed for seven speed values with zero magnetic field. Firstly, the temperature map for magneto-rheological break is computed. Secondly, the temperature value obtained on the outside casing wall is validated against experimental data. Next, the maximum temperature value was identified based on numerical simulation in a point located into the magneto-rheological fluid. The numerical results will be used to improve the magneto-rheological break operation/design.
