A number of visualization experiments are carried out at the laboratory temperature with oil, brine and bacteria suspension for evaluating the performance of MIOR in a glass micromodel. The observations show the effects of bacteria on remaining oil saturation. The interfacial tension reduction, wettability alteration and flow pattern changes are recognized as active mechanisms. COMSOL ...

A clothing system should offer the user a period of relatively comfort. However, changes in the ambient conditions over day affect the heat and mass transport in the system, influencing the user comfort perception. In order to gather information to allow the optimization of clothing systems, it is essential to understand the heat and moisture transfer occurring across multi-layer textiles. For ...

Oxygen-free methane aromatization has been attracting growing attention due to a potential means for producing high valuable products such as aromatics and hydrogen. Many studies have been focused on catalysts screening and characterization, and elementary thermodynamic steps of the reaction. However, little attention has been paid to fluid dynamics which are important for an industrial ...

A three-dimensional mathematical model under stationary conditions have been established to understand the corrosion of carbon steel cylindrical samples immersed in flowing NaCl solution through an annular duct. The migration, diffusion and convection mass transfer mechanisms were solved using the Nernst–Planck equation coupled to the Navier-Stokes equation. A corrosion model based on the mixed ...

The objective of this simulation effort is to develop a mathematical model of vacuum desorption on a POC (Proof of Concept) canister loaded with Zeolite 13X/5A . This canister contains a pelletized adsorption bed which is used to adsorb H2O and CO2. Once this bed is fully saturated with an equilibrium loading, desorption is then accomplished by reducing the pressure to near vacuum. This type of ...

A device for monitoring the oxygen consumption of cells has been developed, which consists of two parts; a cell culturing platform (CCP) and an oxygen sensing chip. The CCP possesses inlet and outlet pipes to direct the fluid under the test to the cell culturing chamber through the inlet pipe and goes out of the outlet pipe after being partially consumed by the cells. In this abstract, the oxygen ...

The transfer of sucrose and fructooligosaccharides to melon and water to solution was modeled based on generalized form of Fick’s second law for simultaneous diffusion and resolved by the finite element method using the software package COMSOL Multiphysics® software. The diffusion coefficients, the mass transfer coefficient and the Biot number were determined using the simplex ...

Oxygen transfer through ceramic membranes at high-temperature can substantially reduce costs respect to conventional separation methods. With the aim to improve the determination of the properties of the ceramic materials, a lab-scale permeation set-up was modeled using the Chemical Engineering Module of COMSOL Multiphysics®. The solution required the coupling of three domains. Gas flow was ...

Extrusion is one of the important manufacturing methods in many industries. In order to obtain the desired product quality and characteristics, the knowledge of the thermal state of the die is very important. In the present study, a two-dimensional conjugate heat transfer model has been developed for non-Newtonian materials being processed in the extrusion die. The modeling equations for the ...

This talk demonstrates the success in teaching chemical engineering undergraduates to use COMSOL Multiphysics (FEMLAB) to solve realistic problems in a project format. Undergraduates have been creative and solved problems much more difficult than those in their textbooks, thus gaining a deeper understanding of transport processes. Illustrations are also given how they check to see they’ve ...
