Effects of Surface Roughness on Dynamic Squeeze Behavior of Partial Journal Bearings with Finite Width
The surface roughness effects on the dynamic squeezing behavior of a finite length partial journal bearing under a time dependent oscillating load is studied. Use Christensen’s stochastic models to develop the stochastic Reynolds’ equation of the longitudinal, transverse and uniform isotropic roughness. According to the results obtained, the roughness pattern, the height of roughness and have s...
متن کاملThermohydrodynamic Characteristics of Journal Bearings Running under Turbulent Condition
A thermohydrodynamic (THD) analysis of turbulent flow in journal bearings is presented based on the computational fluid dynamic (CFD) techniques. The bearing has infinite length and operates under incompressible and steady conditions. In this analysis, the numerical solution of Navier-Stokes equations with the equations governing the kinetic energy of turbulence and the dissipation rate, couple...
متن کاملDesign Of Journal Bearings In Reciprocating Compressors
Journal bearings in hermetic reciprocating compressors are analyzed experimentally as well as numerically. The motor current and the load applied to the bearing are measured to obtain the performance curve of the journal bearing, from which the critical Sommerfeld number is derived. In the numerical analysis, the Reynolds equation and equilibrium equations of the journal center are solved simul...
متن کاملSpecific Features of Aerodynamic Journal Bearings with Elastically Supported Pads
Aerodynamic bearings with elastically supported tilting pads have operational properties comparable with widely-used foil journal bearings. They combine the excellent stability of tilting pad bearings, as a result of very small cross-coupling stiffness terms, with the positive properties of foil bearings, namely their ability to adapt to changing operating conditions and presence of additional ...
متن کاملFlow through the Grooves of Journal Bearings
A simple analysis of fully-developed Stokes ow in grooved bearings is performed that does not use lubrication scaling arguments as in Muijderman (1966). When the inertial terms are ignored, the Navier{Stokes equations decouple. The ow through the groove is then determined from a Poisson equation for the only component of velocity that contributes to the ow through the bearing. This velocity is ...
