[1] Mexican Petroleum Institute, Mexico City, Mexico

A flow and transport model in porous media was implemented in COMSOL Multiphysics® software to simulate, analyze and interpret Microbial Enhanced Oil Recovery (MEOR) processes at core scale under laboratory conditions. The flow model is biphasic and is based on the oil phase pressure and total velocity formulation in which the capillary pressure, relative permeabilities, the effects of ...

Introduction Fluid flow patterns in research or process-scale equipment where a fluid is contained between concentric rotating cylinders in the absence of bulk axial flow has received notable attention in the field of fluid mechanics. Annular flows occur in many practical applications, such as in the production of oil and gas, fluid viscometers, centrifugally-driven separation processes, ...

Simulating the Electrical Double Layer Capacitance

G. Zhang
Clemson University, Clemson, SC, USA

When a solid surface makes contact with a liquid medium, an electrical double layer (EDL) structure forms spontaneously through thermodynamic interaction between electrons and ions. In this study, we developed a computational model using commercial finite element analysis package COMSOL Multiphysics to simulate the double layer structure and quantify the EDL capacitance for the first time. In ...

COMSOL Multiphysics® Simulation of 3D Single-Phase Transport in a Random Packed Bed of Spheres - new

A. Dixon[1]
[1]Department of Chemical Engineering, Worcester Polytechnic Institute, Worcester, MA, USA

Packed beds are important in the chemical industries. Computational fluid dynamics (CFD) can simulate detailed flow and scalar transport in packed beds for improved understanding and quantitative information. We present simulations of single-phase gas flow, conjugate heat transfer and isothermal dispersion of mass in a 3D model of a randomly-packed bed (tube-to-particle diameter ratio = 5.96) of ...

Entropic Evaluation of Dean Flow Micromixers

P. S. Fodor[1], M. Kaufman[1]
[1]Cleveland State University, Cleveland, OH, USA

In this work we investigate computationally the use of spiral channels at Reynolds numbers from 25 to 900 as a mixing structure (Figure 1) using COMSOL Multiphysics, the CFD Module, and the Chemical Species Transport physics. In this system, the centrifugal forces experienced by the fluid as it travels along the curved trajectory induce counter-rotating flows. The presence of these transversal ...

[1]University of Salerno, Department of Industrial Engineering, Fisciano (SA), Italy

Aim of the study is to determine the influence of some of the most important operating variables, especially humidity and temperature, of drying air on the performance of cooking process of pork meat. The process is simulated using finite elements software COMSOL Multiphysics®. The proposed model considers two geometries: cylindrical and parallelepiped, with fixed physical properties and ...

A Wall-Cooled Fixed-Bed Reactor Model for Gas-Phase Fischer-Tropsch Synthesis

A. Nanduri [1], P. L. Mills [1],
[1] Department of Chemical and Natural Gas Engineering, Texas A&M University - Kingsville, Kingsville, TX, USA

In the early 1920’s, Gas-To-Liquids (GTL) and Coal-To-Liquids (CTL) technologies were developed to account for the depleting crude oil resources [1]. During this period, Franz Fischer and Hans Tropsch developed a process to convert synthesis gas (syn gas), derived from coal gasification, to a wide range of high value-added products. This process later came to be known as Fischer-Tropsch (F-T) ...
