Squeeze film lubrication between circular stepped plates of couple stress fluids

Shliomis model based magnetic fluid lubrication of a squeeze film in rotating rough curved circular plates

Magnetic fluid based squeeze film between porous elliptical plates

Archibald [1] analyzed the performance of a squeeze film between various geometrical configurations. Later on Wu [2, 3] investigated a squeeze film behavior for mainly, two types of geometries namely, annular and rectangular. Prakash and Viz [4] developed some aspects of the analysis incorporated in Wu [2, 3] and obtained the load carrying capacity ultimately leading to time height relation for...

Numerical solution of the MHD Reynolds equation for squeeze film lubrication between two parallel surfaces

Characteristic features of squeeze film lubrication between two rectangular plates, of which, the upper plate has a roughness structure, in the presence of a uniform transverse magnetic field are examined. The fluid in the film region is represented by a viscous, incompressible and electrically conducting couple-stress fluid. The thickness of the fluid film region is h and that of the roughness...

Evaluation of Squeeze-film Damping Effects in MEMS Perforated Plates

In this paper, analytical and numerical methods for simulating squeeze-film air damping affecting suspended and perforated movable micro-surfaces are analyzed. Numerical solutions are obtained by full 3-D Navier-Stokes numerical analysis, carried out by a commercial finite element code, COMSOL Multiphysics, and are compared with those obtained using different analytical models proposed in liter...

Boundary lubrication: dynamics of squeeze-out.

The dynamics of the expulsion of the last liquid monolayer of molecules confined between two surfaces (measured recently for the first time) has been analyzed by solving the two-dimensional Navier-Stokes equation combined with kinetic Monte Carlo simulations. Instabilities in the boundary line of the expelled film were observed. We show that the instabilities produce a rough boundary for all le...
