“…Therefore, the CFD methods are applicable in very complex geometries. Gertzos et al, (2008) worked on CFD method of lubricated journal bearing by Bingham lubricant. They solved Navier-Stokes equations by using the FLUENT package and compared the results of the developed 3-D CFD model with theoretical and experimental results of previous investigations, for both Newtonian and Bingham lubricants, and found to be in a very good agreement.…”

“…If the journal is infinitely short, the pressure gradient ∂p/∂z is much larger than the pressure gradient ∂p/∂x , as a result of which the latter can be neglected. The magnetic field is oblique to the stator as in Agrawal [11] and its magnitude is given by where k is a constant to suit the dimensions and the strength of the magnetic field [10]. In 1964, Neuringer and Rosensweig developed a simple model to study the steady flow of magnetic fluids in the presence of slowly changing external magnetic fields.…”

“…It was demonstrated that the magnetic fluid could be used to manufacture active journal bearings. Gertzos et al [10] carried out CFD analysis of hydrodynamic journal bearing lubricated by a Bingham lubricant. The charts presented here could be used by the designer to design smart journal bearings.…”

“…The analysis was based on the numerical solution of the full Navier-Stokes equations by using CFD techniques. Gertzos et al [7] investigated performance characteristics of a hydrodynamic journal bearing lubricated with a Bingham fluid in which three-dimensional (3-D) CFD was applied. Liu et al [8] had applied computational fluid dynamics and fluid structure interaction method to study rotor-bearing system.…”
