Effect of MHD on Porous Circular Stepped Plate Lubricated With Micropolar Fluid

An analysis is made on the effect of magneto hydrodynamics on poro-circular stepped plates lubricated with micropolar fluid. The modified Reynold's equation leads to the development of a closed form expression for pressure, load sustaining capacity, and squeezing time. The impact of porosity is analyzed using the modified Darcy's equation, and the outcomes are compared with the cases of the presence and absence of porosity on the same circular stepped plate. The external magnetic field influences the bearing's efficiency by increasing the pressure, load sustaining capacity, and squeezing time performance. In the presence of porosity, the pressure, load sustaining capacity and squeezing time decrease compared to the absence of porosity, and the comparisons are shown in the tables. The variation of the highly influenced parameter of the bearing system is represented graphically.
