Sažetak
We present a theoretical study of the effect of anisotropic permeability and slip velocity on the action of the squeeze film formed when a secant-shaped circular upper plate with a porous facing approaches an impermeable and flat circular lower plate, considering also rotation of the plates. Expressions for the dimensionless pressure, load capacity and the response time are given by a differential equation. Computed values of dimensionless load capacity and response time are displayed in tabular form. It has been found that they decrease with increasing values of radial permeability, slip parameter and rotational inertia. However, they increase with increasing values of axial permeability and material constant of the Jenkins model. They have also been found to increase when the speed of the lower plate is higher than that of the upper plate.
