Abstract
The present study aims at investigating a couple stress ferrofluid lubricant effects on the performance of the squeezed film when a uniform external magnetic field is applied. For this purpose, Shliomis ferrohydrodynamic and couple stress fluid models are employed. The considered geometry is parallel triangular plates. The effects of couple stress, volume concentration, and Langevin parameters on squeeze film characteristics including time vs. height relationship and load-carrying capacity are investigated. According to the results, employing couple stress ferrofluid lubricant in the presence of the magnetic field leads to an increased performance of the squeeze film.
Highlights
Advances in Tribology film and shear motions, Daliri et al [7] showed that contact load-carrying capacity increases by the presence of magnetohydrodynamic couple stress fluids
Hanumagowda et al [12] studied the effects of viscositypressure dependency on the non-Newtonian squeeze film performance between parallel-stepped circular plates considering effects of surface roughness. ey concluded that the using of couple stress fluid and considering the viscosity-pressure dependency increased the squeeze film characteristics
In a recent study of triangular plates, the effects of viscosity-pressure dependency together with couple stress fluid on the squeeze film characteristics were investigated by AminKhani and Daliri [14]
Summary
Advances in Tribology film and shear motions, Daliri et al [7] showed that contact load-carrying capacity increases by the presence of magnetohydrodynamic couple stress fluids. E present study aims at investigating the couple stress ferrofluid lubricant effects on the performance of the squeezed film once a uniform external magnetic field is available. E effects of couple stress, volume concentration, and Langevin parameters on squeeze film characteristics including time-height relationship and loadcarrying capacity are investigated.
