International Journal for Numerical Methods in Fluids, 2005
AbstractTwo methods for coupling the Reynolds‐averaged Navier–Stokes equations with the q–ω turbulence model equations on structured grid systems have been studied; namely a loosely coupled method and a strongly coupled method. The loosely coupled method first solves the Navier–Stokes equations with the turbulent viscosity fixed.

Extended expansion of the Reynolds equation
Proceedings of the Institution of Mechanical Engineers, Part J: Journal of Engineering Tribology, 2002Principles of a continuously adjustable hydrodynamic bearing concept are outlined and the governing Reynolds equation is given. The equation is non-dimensionalized and expanded taking into account non-uniform variations in the fluid-film thickness. Also given are observations of predicted operating characteristics of one form of the bearing.

The partially wetted bearing—extended Reynolds equation
Tribology International, 2006Abstract The artificial no-slip boundary conditions on the liquid/solid interfaces are traditionally used widely. Due to the advances on the measurement technique and interface sciences, the applications of no-slip boundary conditions on micro-systems are challenged continuously.

Reynolds-Averaged Navier–Stokes Equations for Turbulence Modeling
Applied Mechanics Reviews, 2009The approach of Reynolds-averaged Navier–Stokes equations (RANS) for the modeling of turbulent flows is reviewed. The subject is mainly considered in the limit of incompressible flows with constant properties. After the introduction of the concept of Reynolds decomposition and averaging, different classes of RANS turbulence models are presented, and ...

On The Asymptotic Solution of The Reynolds Equation
SIAM Journal on Applied Mathematics, 1978For, flow at high bearing numbers $\Lambda $, and under suitable physical hypotheses, the problem of determining the pressure distribution in a thin gas film becomes a singular perturbation problem as $\Lambda \to \infty $. We show that, under certain conditions, this problem has a unique solution in a given class.

How the Reynolds equation is related to the Stokes equations
Applied Mathematics & Optimization, 1983Let the Stokes equation being obeyed in a two-dimensional layer bounded by a plane \(y=0 (\Gamma_ 1)\), \(y=\epsilon h(x) (\Gamma_ 3)\) and straight lines \(\Gamma_{2,4}\), \(x=\pm L\). As usually in the boundary layer problem we demand \(\Phi_ y=const\).

ALE formulation of Reynolds fluid film equation
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 2008AbstractThe pressure distribution in hydrodynamic journal bearings is usually calculated by the Reynolds fluid film equation, a linear elliptical partial differential equation. Applying appropriate boundary conditions, e.g., Reynolds boundary conditions, the governing boundary value problem becomes nonlinear.
