Three-Dimensional Thermohydrodynamic Analysis of Journal Bearing Lubricated by Magnetic Fluids with Couple Stresses

Couple stresses because of magnetic particles additives on the lubrication performance a journal bearing system was embraced and scrutinized in current examinations theoretically. The governing equations Reynolds (pressure field), energy (temperature heat conduction field through solids) are coupled solved instantaneously term temperature viscosity. After these set equation pressure is obtained, it used to obtain characteristic. It found that load currying capacity maximum increased due employing fluids along with couple stresses, as well side leakage flow friction coefficient decreased. can be also concluded better lubricant than fluid only (l = 0), Newtonian fluids, stress (ʎ 0).
