Computational fluid dynamics modelling of flow and permeation for pressure-driven membrane processes
... phenomenon. The ability to completely model the flow and concentration phenomena in three-dimensional membrane modules is still not possible. Modern CFD packages have simplified the creation of complex geometries. Their solution algorithms permit efficient and accurate solving by the knowledgeabl ...

A computational fluid dynamics based model of the ex-situ remediation of hydrocarbon contaminated soils
... but hitherto no study has attempted to model the effect on a biopile of its ambient surroundings. This paper presents a Computational Fluid Dynamics (CFD) approach to modelling a biopile under the influence of wind pressure, with and without forced aeration. In addition to the flow, temperature an ...

CFD simulation of fluid flow through spacer-filled membrane module: selecting suitable cell types for periodic boundary conditions
In this study, the appropriate cell type for periodic boundary conditions (PBC) in CFD analysis for spacerfilled membrane module design was validated by comparing the simulated values of pressure drop with that obtained by experiments.
