The flow of a synovial fluid modelled as a couple-stress fluid in a squeeze film biological bearing with a permeable layer is considered. The biobearing is modelled by two rotational surfaces and the permeable layer is adhered to the curved impermeable surface. The flow in a squeeze film biobearing is considered with inertia and the Navier-Stokes and Poisson equations are uncoupled by using the Morgan-Cameron approximation. The flow of a couple-stress fluid in permeable layer satisfies the modified Darcy's law. As an example the biological bearing modelled by two parallel surfaces is discussed.
