Numerical Analysis of Inner Flow Field for Disk MRF Brake

Abstract:

According to structure of disk MRF brake computational model of inner flow field for MRF was set up at simplified condition when MRF was regarded as Bingham model. Velocity distribution in inner flow field had been analyzed at different brake velocities and magnetic intensity using finite volume method (FVM), and brake torque and power had also been received at the same condition by integral method. Numerical analysis data were compared with theoretical data. Result showed that velocity distribution of inner flow field was not linear at axial direction, and that brake torque of disk MRF brake was constant approximately, and that numerical data and theoretic data were identical and it can provide reference for design.
