Numerical analysis of the hydrodynamic behavior of a magnetoreological fluid

Abstract

In this work, a numerical analysis of the behavior of magnetorheological fluids under the influence of different magnitudes of magnetic field is carried out. The properties of these fluids are affected and modified through the application of these magnetic fields, which has many applications in the engineering area. To carry out the analysis, a circular geometry is taken on which the magnetic field acts perpendicular to the direction of movement of the fluid. The magnetorheological fluid used is Basonetic 5030. The inlet velocity of the fluid is considered to be 1.31 m/s for the geometry of 20 and 30 mm, respectively. The Bingham viscosity model is used to obtain the viscosity. For the numerical solution is used a commercial software, in which has been used a UDF for the application of the Bingham viscosity model. Among the reported results is the velocity profile and the pressure drop along the duct for magnetic fields of 0.01 to 0.5 Teslas, here is observed the influence of the magnetic effects on the magnetorheological fluid with different diameters.
