Analysis of an Elasto-Hydrodynamic Seal by Using the Reynolds Equation

open access: yesApplied Sciences, 2022
This paper reports numerical studies of an Elasto-Hydrodynamic (EHD) seal, which is being developed for supercritical CO2 (sCO2) turbomachinery applications. Current sCO2 turbomachinery suffers from high leakage rates, which is creating a major roadblock

The asymptotic behavior for the Navier-Stokes-Voigt-Brinkman-Forchheimer equations with memory and Tresca friction in a thin domain

open access: yesDemonstratio Mathematica
In this article, we investigate the behavior of weak solutions for the three-dimensional Navier-Stokes-Voigt-Brinkman-Forchheimer fluid model with memory and Tresca friction law within a thin domain. We analyze the asymptotic behavior as one dimension of

A rigorous justification of the Reynolds equation [PDF]

open access: yesQuarterly of Applied Mathematics, 1987
A small parameter technique is used to derive Reynolds’ lubrication equation from the Stokes equation. The error associated with the approximation is estimated in suitable norms.

Effects of the Control Parameters on the Stability of a Laminar Boundary Layer on a Porous Flat Plate

open access: yesInternational Journal of Applied Mechanics and Engineering, 2021
This work is devoted to the analysis of the linear temporal stability of a laminar dynamic boundary layer on a horizontal porous plane plate. The basic flow is assumed to be laminar and two-dimensional.

On the Reynolds number expansion for the Navier–Stokes equations [PDF]

open access: yesNonlinear Analysis: Theory, Methods & Applications, 2014
In a previous paper of ours [Nonlinear Anal. 2012] we have considered the incompressible Navier-Stokes (NS) equations on a d-dimensional torus T^d, in the functional setting of the Sobolev spaces H^n(T^d) of divergence free, zero mean vector fields (n > d/2+1).

Thrust Bearing with Rough Surfaces Lubricated by an Ellis Fluid

open access: yesInternational Journal of Applied Mechanics and Engineering, 2014
In the paper the influence of bearing surfaces roughness on the pressure distribution and load-carrying capacity of a thrust bearing is discussed. The equations of motion of an Ellis pseudo-plastic fluid are used to derive the Reynolds equation.

Large Deviation Approach to the Randomly Forced Navier-Stokes Equation [PDF]

open access: yes, 2003
The random forced Navier-Stokes equation can be obtained as a variational problem of a proper action. By virtue of incompressibility, the integration over transverse components of the fields allows to cast the action in the form of a large deviation ...

Computation of unsteady momentum and heat transfer from a fixed circular cylinder in laminar flow [PDF]

open access: yes, 2003
This paper presents a finite difference solution for 2D, low Reynolds number, unsteady flow around and heat transfer from a stationary circular cylinder placed in a uniform flow. The fluid is assumed to be incompressible and of constant property.
