Investigating the Mean Residence Time in a Two-Phase Oil-Water Separator Using Volume of Fluid Multiphase Theory in Computational Fluid Dynamics Simulation

SPE Production & Operations, 2023
Multiphase separators are essential to chemical units, especially in the oil and gas industry. Because separators are usually the first equipment installed in the oil and gas units, their performance directly affects other equipment.

Relationship between residence time, fluid dynamics and efficiency in countercurrent flow equipment

Chemical Engineering & Technology, 1988
AbstractThe suitability of any item of equipment for a given thermal separation process cannot always be judged solely in the light of efficient and loading range data. In vacuum rectification, involving a large number of theoretical stages, the vapour pressure drop per transfer unit exerts a considerable effect on the energy consumption and thus ...

Determining possible thrombus sites in an extracorporeal device, using computational fluid dynamics-derived relative residence time

Computer Methods in Biomechanics and Biomedical Engineering, 2014
The prediction of conditions that may result in thrombus formation is a useful application of computational fluid dynamics. A number of techniques exist, based on the consideration of wall shear stress and regions of low blood flow; however, no clear guideline exists for the best practice of their use.

Studying human exposure to vehicular emissions using computational fluid dynamics and an urban mobility simulator: The effect of sidewalk residence time, vehicular technologies and a traffic-calming device

Science of The Total Environment, 2019
A computational system consisting of an urban mobility simulator, validated fluid dynamics and an integral exposure model, is proposed to obtain cyclist and pedestrian exposure to PMx and NOx. Pedestrian activities in the urban anthroposphere include walking and running.

Computational Fluid Dynamics Modeling of a Bench-scale Pump−Mixer:  Head, Power and Residence Time Distribution

Industrial & Engineering Chemistry Research, 2007
The present work involves several single-phase computational fluid dynamics (CFD) simulations of a continuous-flow bench-scale pump−mixer that uses a top-shrouded turbine with trapezoidal blades. Baffle−impeller interaction has been modeled using the sliding-mesh approach. The standard k−e model has been used for turbulence modeling.
