Sc. Sharma et al., Static and dynamic performance characteristics of orifice compensated hydrostatic flexible journal bearings with non-newtonian lubricants, TRIBOL T, 44(2), 2001, pp. 242-248
The combined effect of non-Newtonian lubricant behavior and bearing shell f
lexibility on the performance of an orifice compensated multirecess hydrost
atic/hybrid journal bearing system is studied. The analysis considers the c
onstitutive equations for the flow of a non-Newtonian lubricant through on
orifice restrictor, the generalized Reynold's equation governing the flow o
f lubricant having variable viscosity, and 3-D elasticity equations. The co
mputed results demonstrate that loss in hearing performance due to the pseu
do-plastic effect of the non-Newtonian lubricant can be mitigated by a prop
er selection of parameters such as the deformation coefficient ((C) over ba
r (d)) and non-linearity factor ((K) over bar) or power law index (n).
