Effects of manufacturing errors on the static characteristics of aerostatic journal bearings with porous restrictor
TL;DR: In this article, the effects of manufacturing errors on the static performance of aerostatic porous journal bearings were investigated by solving the Darcy-Forchheimer law and Navier-Stokes equations.

Deformation and flying height orbit of glass sheets on aerostatic porous bearing guides
TL;DR: In this paper, the deformation behavior and the orbit of the flying height of glass sheets on porous bearing pads during the feeding process were investigated using the compressible Reynolds equation and Timoshenko's thin film theory.

Permeability and Inertial Coefficients of Porous Media for Air Bearing Feeding Systems
TL;DR: In this paper, an experimental and theoretical investigation of porous resistances used in gas bearing and thrust pad supply systems is presented. And the results from set-up a) were then used to obtain experimental permeability and to determine the inertial coefficients, which were expressed as a function of the Reynolds number.

Effect of the deformation of porous materials on the performance of aerostatic bearings by fluid-solid interaction method
TL;DR: In this paper, the effect of supply air pressure, material thickness, and Young's modulus on the deformation of aerostatic porous bearing is analyzed. And a double-layered porous restrictor is proposed to suppress deformation and various thickness combinations of double layers are also discussed.

Boundary conditions at a naturally permeable wall
TL;DR: In this article, a simple theory based on replacing the effect of the boundary layer with a slip velocity proportional to the exterior velocity gradient is proposed and shown to be in reasonable agreement with experimental results.

The Flow of a Viscous Fluid through a Porous Wall into a Narrow Gap : A Consideration of the Slip of Fluid on a Porous Wall Surface
Shingo Ishizawa,Eiichi Hori +1 more
TL;DR: In this paper, an exact theoretical analysis for axi-symmetric flow of a viscous fluid through a porous wall into a narrow, uniform gap is presented. But the analysis is restricted to the case where the fluid may flow radially in the porous medium and slip on the porous wall surface.
