New Continuous Model of Reynolds Equation for Gas Film Lubrication
Advanced Materials Research, 2010Started from a widely used FK model of Reynolds equation, a new simplified model, called continuous FK (CFK) model, is proposed to simulate the ultra-thin air bearing film in hard disk drives (HDDs). The new model of Reynolds equation possesses simpler mathematical form than that of FK model.

Exact solutions of non-linear Reynolds' gas lubrication equations
Wear, 1976Abstract The Reynolds second order non-linear differential equation, which governs the pressure distribution between two non-parallel surfaces in relative motion constituting a gas slider bearing system, contains a parameter ϵ and a function h(x) describing the bearing geometry.

Towards a Reynolds Equation for Gas Lubricated Bearings When Contact Occurs
Journal of Tribology, 2001The various existing forms of Reynolds equation are known to yield pressure fields which are unbounded and nonphysical when contact occurs. With a view to developing a Reynolds equation that is suitable for contact, here we revisit Taylor’s plate scraping problem for incompressible flow.

The three-dimensional Reynolds equation for micro-polar-fluid-lubricated bearings
Wear, 1982Abstract The three-dimensional Reynolds equation for micropolar fluids is derived. The balance equations for micropolar fluids are simplified by using traditional lubrication assumptions and order-of-magnitude analysis. The simplified equations are solved to yield expressions for the velocity distribution and the microrotation velocities.

High-pressure rheology of lubricants and limitations of the Reynolds equation
Tribology International, 1998Abstract A review of high pressure rheology leads to the conclusion that the results from rheometers may be used to generate empirical rate equations which are useful in modelling elastohydrodynamic traction. However, an analytical treatment of piezoviscous liquids reveals that the Reynolds equation adequately captures the mechanics of the ...

The Physics of Fluids
During the operation of rim-driven thrusters (RDTs), eccentricity between the journal and water-lubricated bearing (WLB), as well as between the motor's stator and rotor, is commonly observed.

Generalized Reynolds and integrated energy equations for fluid-film lubrication
International Journal of Non-Linear Mechanics, 1981Abstract A generalized form of Reynolds equation governing pressure distribution and an integrated form of energy equation in the fluid-film between porous bounding walls has been developed from fundamental equations of thermohydrodynamics with a minimum number of restricting assumptions and slip conditions.

A modified nonlinear Reynolds equation for thin viscous flows in lubrication
Asymptotic Analysis, 2007We derive a nonlinear second-order differential equation for the pressure approximation in hydrodynamic lubrication. This equation, in contrast to the classical Reynolds equation, takes into account both the inertial and the curvature effects and its solution corresponds to the first two terms in the asymptotic pressure expansion.

A comparison study between navier-stokes equation and reynolds equation in lubricating flow regime
KSME International Journal, 2003For practical calculations, the Reynolds equation is frequently used to analyze the lubricating flow. The full Navier-Stokes Equations are used to find validity limits of Reynolds equation in a lubricating flow regime by result comparison. As the amplitude of wavy upper wall increased at a given average channel height, the difference between Navier ...
