MULTIGRID SOLUTION TO ANALYZE THE EFFECT OF ROUGHNESS FOR MODIFIED REYNOLDS EQUATION

An attempt is made to understand the significance of unevenness amidst dual lateral surfaces. For this physical configuration magnetic field is applied in cross wise direction. The structure describes that the top portion has irregular covering and descending plate is covered by porous material. To avoid friction, taking into account of contribution of couple-stress fluid is highlighted in this work. The governing equation for this configuration is resolved by desirable boundary conditions. The phenomenal modified Reynolds equation is resolved by adopting one of the leading techniques finite difference based multigrid method. As a result the roughness parameter is discussed relative to numerous values of couple-stress limitations, Hartmann number and aspect ratio to analyze bearing attributes like pressure dissemination and weight bearing capacity. The results and conclusions are summarized with various graphs.
