A continuum model of multi-phase reactive transport in igneous systems [PDF]
, 2019 Multi-phase reactive transport processes are ubiquitous in igneous systems. A challenging aspect of modelling igneous phenomena is that they range from solid-dominated porous to liquid-dominated suspension flows and therefore entail a wide spectrum of ...

Porous Hydrodynamic Journal Bearing Analysis Using Micropolar Fluid in Steady-State Condition
Tribology Online, 2019 The objective of the present work is to study theoretically, the steady-state performance of finite hydrodynamic porous journal bearings under micropolar lubrication. The fluid pressure in porous matrix follows Darcy’s equation.

Prediction of the lifespan of cement at a specific depth based on the coupling of geomechanical and geochemical processes for CO2 storage [PDF]
, 2019 The injection of carbon dioxide (CO2) captured from combustion-based processes into underground formations is one of a number of plausible methods to reduce its release into the atmosphere and consequential greenhouse gas warming.

Hydromagnetic Squeeze Film in Rough Porous Narrow Journal Bearing: A Study of Slip Effect
Tribology Online, 2017 This article aims to study the influence of slip on a hydromagnetic squeeze film in transversely rough porous narrow journal bearing. The Neuringer-Rosensweig model governs the fluid flow. The slip model of the Beavers and Joseph has been used.

Hydrodynamic lubrication of porous journal bearings with a grease.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1985 Porous materials find a wide range of applications as bearing metals because of their self-lubricating action. On the other hand, grease its widely used as a lubricant for porous metal bearings because of its simplicity of application. Unfortunately, since the governing law for flows of grease in porous matrices, that is Equivalent to Darcy's law for ...
