Analysis of Infinitely Short and Infinitely Long .

Infinitely long-bearing and infinitely short bearing solutions are the two available approximate closed form solutions for journal bearings. In the present investigation, solution of Reynolds equation i.e. pressure profile is compared with pressure profile obtained by previously used approximate method like finite difference method (FDM).

Hydrodynamic coupling of two sharp-edged beams vibrating .

In this paper, we study flexural vibrations of two thin beams that are coupled through an otherwise quiescent viscous fluid. While most of the research has focused on isolated beams immersed in placid fluids, inertial and viscous hydrodynamic coupling is ubiquitous across a multitude of engineering and natural systems comprising arrays of flexible structures.

Influence of short grooves on hydrodynamic lubrication of .

This work is conducted to investigate the effect of the geometrical parameters of the short grooves on hydrodynamic lubrication for infinitely long textured sliders under a given set of operating parameters. Geometrical parameters such as the short groove width, depth, length, and spacing are studied using the numerical simulation method.

Abstract This paper presents numerical solution to the pressure distribution of a fluid in a hydrodynamically lubricated journal bearing using the classical Reynolds equation that models the effect of side or end leakage i.e., there is flow in the z-direction in bearings. The finite element method was used to analyze the flow. Two dimensional interpolation functions were used in the modelling ...

In this work, a parametric study of the change in lubricant viscosity with pressure variation of fluid (lubricant) in a hydrodynamic journal bearing was carried out. This study was carried out using the Finite Element Method (FEM) and this was used to analyse the pressure behaviour of the bearing was presented using the classical Reynolds Equation.
