Abstract

The Navier-Stokes equations were modified by adopting the non-linear turbulence theory proposed by Constantinescu to take into account the turbulent stresses. The modified equations were solved by the finite element method using Galerkin's technique and a suitable iterative procedure.

The performance characteristics of a finite hydrodynamic journal bearing (aspect ratio b = 1) were studied in terms of the load-carrying capacity, non-dimensional stiffness and damping coefficients and critical journal mass at various eccentricities for Reynolds' numbers up to 13 300. The computed results are compared with those obtained using the twodimensional triangular element formulation and the linearized turbulence theory.

On the stability of a rigid rotor in turbulent finite hydrodynamic journal bearings
1992, Wear
The stability characteristics of finite journal bearings in turbulent regime were investigated theoretically, following Constantinescu's turbulent lubrication theory. Stability curves were drawn for different slenderness ratios for Reynolds numbers up to 50 000. Computed results are compared with published results (H. Hashimoto, S. Wada and J.-I. Ito, J. Tribol. Trans. ASME, 109 (1987) 307). Turbulence causes the stability of the rotor to deteriorate. However, the stability of the rotor improves with a decrease in the L/D ratio of the bearing.
Prediction of the coefficient of friction of a misaligned turbulent flow journal bearing
1988, Tribology International
This paper offers computer solutions for a misaligned journal bearing operating in the turbulent regime. The modified Reynolds equation is solved numerically taking into consideration that the distribution of effective viscosity is dependent on local shear stress. The performance characteristics of finite hydrodynamic journal bearings are studied at various eccentricities for different degrees of misalignment up to a maximum value, which defines a journal bearing contact at one end. An empirical formula for the prediction of the coefficient of friction is established, in terms of the nondimensional load capacity and the degree of misalignment.
