Abstract:
The effects of location and shape of a localised corrugation on the
performance of a fixed inclined slider bearing are investigated numerically,
using a finite element method. It is shown that normal force
increases uniformly as the corrugation is relocated downstream in the
bearing gap, from being less than that of the smooth walled case to
being higher, while flow rate decreases, also uniformly. Corrugation
with the shape of rectangle waves produce largest changes in pressure
distribution, normal force and flow rate, relative to the smooth walled
case. This is followed by sine-wave corrugation, whereas triangle-wave
corrugation produces smallest changes. The number of corrugation
waves produces similar, but weaker, changes in normal force and flow
rate, to the corrugation volume, when this is used as a parameter
characterizing corrugation shape.
