Rheological Properties of a Honge Oil-based Magnetorheological Fluid used as Carrier Liquid

Developing a sudden damping and its control which is demanded in many engineering applications with the existing conventional methods are difficult and critical too. A magnetorheological (MR) fluid with good rheological properties can exhibit very Cast damping characteristics and can be controlled just by varying the applied magnetic field to that fluid. Thus in this paper, a MR fluid is proposed with a non-edible vegetable oil such as Honge oil as a carrier liquid. Three samples of such MR fluid containing different percentages by volume of carbonyl iron powder as suspensions are prepared for comparing their rheological properties. An experimental setup consisting of a capillary viscometer with a pair of solenoid type of electromagnetic coils is developed. The rheological properties of the proposed MR fluid are investigated under the application of different magnetic fields and the results are presented. It was observed that the one of the samples containing 40 per cent by volume as suspensions exhibits a maximum viscosity of 334 Pa-s and yield stress of 13.23 kPa at a magnetic field of 0.3816 T. The results have been compared with those obtained by other researchers.
