Linearity of the Co-moving Velocity

open access: yesTransport in Porous Media
AbstractThe co-moving velocity is a new variable in the description of immiscible two-phase flow in porous media. It is the saturation-weighted average over the derivatives of the seepage velocities of the two immiscible fluids with respect to saturation.

The impact of wettability on the co-moving velocity of two-fluid flow in porous media [PDF]

open access: yes, 2023
The impact of wettability on the co-moving velocity of two-fluid flow in porous media is analyzed herein. The co-moving velocity, developed by Roy et al. (2022), is a novel representation of the flow behavior of two fluids through porous media. Our study

Some comments on mapping the combined effects of slurry concentration, impact velocity and electrochemical potential on the erosion–corrosion of WC/Co–Cr coatings [PDF]

open access: yes, 2008
Materials exposed to aqueous slurry environments must not only resist the impact of solid particles and the flowing environment but also the degradation caused by electrochemical corrosion.

Questions of constructing probe active control devices for product sizes [PDF]

open access: yesОмский научный вестник, 2018
The article presents probe active control devices (ACD) of the size of products, describes the composition, versions, principle and modes of operation. The measurements are carried out by two-coordinate vibration oscillations of the tip along a closed

The break-up tendency of long rod projectiles

open access: yesDefence Technology, 2016
A model for the tendency of fragmentation of a long rod projectile subjected to armour components in add-on armours such as reactive armour and active protection systems is presented. The model is based on studies of the interaction between a cylindrical

Velocity-Potential Boundary-Field Integral Formulation for Sound Scattered by Moving Bodies [PDF]

open access: yes, 2018
This paper presents a boundary-field integral formulation suitable for the prediction of noise scattered by moving bodies. Although based on the same flow modeling assumptions, linear formulations derived from velocity potential or pressure disturbance ...
