In recent decades, problems related to the squeeze of fluid films in the presence of a
porous medium draw attention of researchers and are the subject of many applied studies
for industry and biomechanics. Our concerns in this paper are the numerical simulation of
the viscous shear stresses effects on the fluid film characteristics between two discs
with one porous. This study is based on the coupling, at the fluid film-porous disc
interface, of the Darcy-Brinkman equations in the porous medium and the modified Reynolds
equation describing the flow in the fluid film. The system of equations obtained is
discretized by the means of finite differences method and solved numerically using the
technique of Successive Over-Relaxation (SOR). The results show that the viscous shear
effects increase the radial and the axial fluid film velocities as well as the squeeze
film velocity but decrease the response time. Moreover, these effects are enlarged for
smaller viscous shear parameter and for smaller fluid film thickness.
