A modification on velocity terms of Reynolds equation in a spherical coordinate system
Tribology International, 2019 The widely-used Reynolds equation to simulate fluid lubrication in hip implants by Goenka and Booker has velocity terms accounting just for the rotational motion of the femoral head.

Asia-Pacific Journal of Chemical Engineering, Volume 21, Issue 1, January/February 2026.ABSTRACT The utilisation of viscoelastic Walter's B nanoliquid in engineering and biomedical applications gained substantial attention because of its ability to provide real‐time fluid behaviour, particularly in the heat flow mechanism. In particular, the flow of viscoelastic fluid over an elongating surface is useful in polymer processing and ...

Basic lubrication equations [PDF]
Lubricants, usually Newtonian fluids, are assumed to experience laminar flow. The basic equations used to describe the flow are the Navier-Stokes equation of motion.

Breakup of diminutive Rayleigh jets [PDF]
, 2010 Discharging a liquid from a nozzle at sufficient large velocity leads to a continuous jet that due to capillary forces breaks up into droplets. Here we investigate the formation of microdroplets from the breakup of micron-sized jets with ultra high-speed

Derivation of the Reynolds equation for lubrication of a rotating shaft [PDF]
Archivum Mathematicum, 2000 In this paper, using the asymptotic expansion, we prove that the Reynolds lubrication equation is an approximation of the full Navier– Stokes equations in thin gap between two coaxial cylinders in relative motion. Boundary layer correctors are computed. The error estimate in terms of domain thickness for the asymptotic expansion is given. The corrector

Free surface flows with large slopes: beyond lubrication theory
, 2006 The description of free surface flows can often be simplified to thin film (or lubrication) equations, when the slopes of the liquid-gas interface are small.

Flow Regulation in a T‐Shaped Mixing Channel Using a Proportional‐Integral‐Derivative Controller
The Journal of Engineering, Volume 2026, Issue 1, January/December 2026.This study investigates mixed convection in a 2D T‐shaped channel with a heated cylinder, employing a PID controller to regulate airflow and maintain consistent outlet temperatures. Using the Galerkin finite element method (GFEM), the effects of varying PID parameters on system stability and response time are analysed.

Derivation of Rarefaction-Modified Reynolds Equation Considering Porosity of Thin Lubricant Film
Journal of Tribology, 1996 A new lubrication model is derived for solving ultra-thin gas lubrication problems encountered in the analysis of a magnetic head slider flying over a magnetic disk coated with giant-molecule lubricant film. In this model, the liquid lubricant film is replaced with a permeable material, and the boundary between the gas and liquid is subject to two ...
