In the present study, a modified Reynolds equation including the electrical double layer (EDL)-induced electroviscous effect of lubricant is established to investigate the effect of the EDL on the hydrodynamic lubrication of a 1D slider bearing. The theoretical model is based on the nonlinear Poisson-Boltzmann equation without the use of the Debye-Hückel approximation. Furthermore, the variatio...

By means of the physical process-based modeling approache to computing coastal and estuarine hydrodynamic and morphodynamic processes, an integrated model system was developed to simulate tides, waves, currents, winds, sediment transport, and morphological changes in coastal and estuarine regions. This paper presents an overview of this integrated morphological process modeling system consistin...

background and aims: adenovector gene transfer induces inflammatory response that finally leads to vector removal from delivered site. the effect of hydrodynamic pre-injection on adenovector mediated liver inflammation remained elusive. materials and methods: different mice groups were pre-treated by hydrodynamic saline, dexamethasone or nothing prior to adeno-luciferase administration. their s...

We consider the equation modeling the compressible hydrodynamic flow of liquid crystals in one dimension. As mentioned in [12], the weak solution was obtained with the initial density having a positive lower bound and Hintegrable. In this paper, we get a weak solution with initial density nonnegative and L-integrable.

We consider the equation modeling the compressible hydrodynamic flow of liquid crystals in one dimension. When the initial density function ρ0 has a positive lower bound, we obtain the existence and uniqueness of global classical, and strong solutions and the existence of weak solutions. For ρ0 ≥ 0, we obtain the existence of global strong solutions.

This paper is devoted to the numerical modeling and simulation of hydrodynamic and dissipation processes in damper systems, where the working element is a magnetic fluid drop around a permanent magnet. Flow patterns and dimensionless dissipation coefficient depending on the Reynolds number and magnet position are established. r 2004 Elsevier B.V. All rights reserved. PACS: 02.60.Cb; 02.70.Dh; 4...

in this study, liquid-liquid extraction process in a kuhni extraction column was modeled and simulated. a non-equilibrium dynamic model was developed for modeling liquid-liquid extraction processes based on a rate-based model. the model equations are inclusive of partial and ordinary differential equations which were discretized in column height direction. the population balance model was used ...
