Resumen

This work investigates, using a couple stress fluids, the combined impacts of MHD and slip velocity on the lubrication performance of curved-circular flat surfaces with the effect of porous-rough bearing. Derived and investigated under several operating situations are expressions for MHD squeeze film pressure, load capacity, and squeeze film time. Results imply that an external magnetic field helps the squeeze film properties to become better in an electrically conducting non-Newtonian fluid. Whereas radial roughness lowers these features relative to smooth surfaces, azimuthal surface roughness enhances them. Emphasizing the limits of porous materials, the permeability parameter negatively affects pressure, load capacity, and squeeze-film time. These results progress understanding of lubrication performance under MHD impacts in complex systems.
