2D Computational Fluid Dynamics Analysis into Rotational Magnetorheological Abrasive Flow Finishing (R-MRAFF) Process

摘要

Rotational magnetorheological abrasive flow finishing is a nano-finishing technique used to finish hard and complex materials. By R-MRAFF, high grade surface finish can be achieved with close tolerances and without damaging surface topography. R-MRAFF works on the comparative movement among the magnetorheological fluid, and the workpiece surface attends the high surface quality. This article deals with the finite element analysis on behavior of magnetorheological fluid on workpiece in the influence of the magnetic field. In this work, a 2D computational fluid dynamics simulation in ANSYS FLUENT is performed to analyze the stresses generated due to magnetorheological fluid on workpiece and effect of concentration of carbonyl iron particles on surface roughness.
