Effect of microchannel aspect ratio on residence time distributions and the axial dispersion coefficient [PDF]
Chemical Engineering and Processing: Process Intensification, 2009 The effect of microchannel aspect ratio (channel depth/channel width) on residence time distributions and the axial dispersion coefficient have been investigated for Newtonian and shear thinning non-Newtonian flow using computational fluid dynamics.

Abstract Fluid dynamic characterization for a set of three serial rectangular based spouted beds (RBSB) using sawdust or turnip seeds, were made. In batch experiences, the minimum spouting velocity (Ums) and the maximum pressure drop (ΔPmax) were determined based on the bed height and moisture content.

Computational fluid dynamic prediction of the residence time distribution of a prototype hydrodynamic vortex separator operating with a base flow component [PDF]
Proceedings of the Institution of Mechanical Engineers, Part E: Journal of Process Mechanical Engineering, 2005 A hydrodynamic vortex separator (HDVS) has been modelled using computational fluid dynamics (CFD) in order to accurately determine the residence time of the fluid at the two outlets of the HDVS using a technique that was developed for use in heating, ventilation, and air conditioning (HVAC). The results have been compared with experimental data [1]. It

International Journal of Chemical Reactor Engineering, 2012 Abstract The continuous operation of a stirred tank reactor for styrene polymerization was modeled. The proposed approach consists of an iterative procedure between two modules that considers the fluid-dynamics and kinetics respectively. The kinetic module considers a complex kinetic mechanism and is used to predict the time evolution

Summary 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. A two-phase oil-water separator was investigated in this study.
