Dissipative Particle Dynamics and other particle methods for multiphase fluid flow in fractured and porous media
Paul Meakin, Zhijie Xu
Particle methods are less computationally efficient than grid based numerical solution of the Navier Stokes equation. However, they have important advantages including rigorous mas…
Investigation of countercurrent flow profile and liquid holdup in random packed column with local CFD data
Yucheng Fu, Jie Bao, Rajesh Kumar Singh +2
Liquid holdup and mass transfer area are critical parameters for packed column design and CO2 capture efficiency prediction. In this paper, a framework was established for modeling…
Hydrodynamics of countercurrent flows in a structured packed column: effects of initial wetting and dynamic contact angle
Rajesh Kumar Singh, Jie Bao, Chao Wang +2
Computational countercurrent flow investigation in the structured packed column is a multiscale problem. Multiphase flow studies using volume of fluid (VOF) method in the represent…
Direct effect of solvent viscosity on the physical mass transfer for wavy film flow in a packed column
Zhijie Xu, Rajesh Kumar Singh, Jie Bao +1
The interphase mass transfer plays a critical role in determining the height of packed column used in the absorption process. In a recent experiment (Song D. Ind. Eng. Chem. Res. 2…
Upscaling of Solute Transport in Heterogeneous Media with Non-uniform Flow and Dispersion Fields
Zhijie Xu, Paul Meakin
An analytical and computational model for non-reactive solute transport in periodic heterogeneous media with arbitrary non-uniform flow and dispersion fields within the unit cell o…
Method of model reduction and multifidelity models for solute transport in random layered porous media
Zhijie Xu, Alexandre M. Tartakovsky
This work presents a hierarchical model for solute transport in bounded layered porous media with random permeability. The model generalizes the Taylor-Aris dispersion theory to st…
A Consistent Spatially Adaptive Smoothed Particle Hydrodynamics Method for Fluid-Structure Interactions
Wei Hu, Guannan Guo, Xiaozhe Hu +3
A new consistent, spatially adaptive, smoothed particle hydrodynamics (SPH) method for Fluid-Structure Interactions (FSI) is presented. The method combines several attributes that…
