Magnetohydrodynamics analysis of magnetorheological fluid damper

A key feature of magnetorheological fluid is its variability rheological properties in which upon exposing this fluid, the viscosity changes accordingly. Hence nature can be implemented various engineering applications. To understand influence a (MR) damper, it essential to study flow behaviour using computational and numerical methods. The main objective work estimate external magnetic field on velocity inside damper magnetohydrodynamic analysis. Finite element analysis, magnetostatic (MHD) analysis have been carried out investigate change shape profile across gap monotube MR under magnitude force MHD module ANSYS fluent software. simulation conducted by considering laminar, steady-state, incompressible flow. In finite flux density (MFD) ‘B’ was evaluated at direct currents. Later, obtained MFD has applied perpendicular direction fluid. effective length exposed taken as 2 mm 28 an overall 30 mm. extracted results shown that reduces with increase density. It observed 10.42 % reduction increasing from 0.25 T 1 75 kPa pressure. reason for because variation field, very much produce good damping effect damper.
