Magnetic fluid brake

The paper presents a series of theoretical and experimental results concern ing the influence of an exterior magnetic held of various configurations an d intensities over a power dissipated by a disk brake in magnetic liquid. T he formula of the dissipated power and the influence of magnetic field over this for regimes of laminar and turbulent flow of the liquid has been dete rmined. The conclusions resulted from the interpretation of the experimenta l results confirm the theoretical aspects explained in the paper. (C) 1999 Elsevier Science B.V. All rights reserved.
