Dynamic sealing principles [PDF]

The fundamental principles governing dynamic sealing operation are discussed. Different seals are described in terms of these principles. Despite the large variety of detailed construction, there appear to be some basic principles, or combinations of ...

Dual Solutions of Non‐Newtonian Micropolar Nanofluid Flow and Heat Transfer Over a Stretching/Shrinking Surface With Chemical Reaction and Lorentz Forces

Engineering Reports, Volume 8, Issue 4, April 2026.
This plot represents the flow configuration of the two‐phase nanofluid model. The dynamics of boundary layer micropolar nanofluid flow, heat and mass transfer characteristics past a vertical exponentional stretching/shrinking sheet in the presence of chemical reaction and thermal raditaion effects are investigated. In addition, the Lorentz and buoyancy

Influence of surface roughness and waviness on film thickness and pressure distribution in elastohydrodynamic contacts [PDF]

The Christensen theory of a stochastic model for hydrodynamic lubrication of rough surfaces was extended to elastohydrodynamic lubrication between two rollers.

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.

Soft lubrication: the elastohydrodynamics of non-conforming and conforming contacts

, 2004
We study the lubrication of fluid-immersed soft interfaces and show that elastic deformation couples tangential and normal forces and thus generates lift. We consider materials that deform easily, due to either geometry (e.g.

Effects of the finite particle size in turbulent wall-bounded flows of dense suspensions

, 2018
We use interface-resolved simulations to study finite-size effects in turbulent channel flow of neutrally-buoyant spheres. Two cases with particle sizes differing by a factor of 2, at the same solid volume fraction of 20% and bulk Reynolds number are ...
