O objetivo deste trabalho foi modelar a perda de umidade de bananas Caturra com os modelos empíricos e com o software COMSOL Multiphysics, definindo os coeficientes convectivo de transferência de massa e difusivo. O valor obtido para coeficiente de difusão, com base no ajuste matemático da 2ª Lei de Fick para cilindros foi de 1,89.10-9 m²/s. O valor do coeficiente convectivo de transferência de ...

Hydrophobic meshes are a new, promising technique for the recovery of spilled oil in the ocean. They allow to recover and store oil, while filtering it from the surrounding water. They are clean, efficient and can be used in continuously. These meshes have one drawback, however: if they are submerged too deep under the water level, the high pressure will cause presence of water in the recovered ...

Mechanistic Modeling of Non-Spherical Bacterial Attachment on Plant Surface Structures

[1] Cornell University, Ithaca, NY, USA

The particle tracking model provided a deeper understanding to the experimental results. The model showed good agreement with experimental data for rotation, transport and attachment. In the attachment model, protrusions create low velocity, low shear regions increasing attachment while holes pull cells toward the surface and increase residence time on the surface increasing attachment rate.

Modelling of the Oxygen Consumption of Cells in the Cell Culturing Platform - new

A. Niazi[1]
[1]School of Mechanical Engineering, University of Birmingham, Birmingham, United Kingdom

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 ...

Numerical Modeling of Subsurface CO2-Storage

E. Holzbecher [1],
[1] German University of Technology in Oman (GUtech), Halban, Oman

A model for CO2 storage is presented. It is shown that the system is highly dynamic, i.e. results depend strongly on parameter disturbances and numerical features. However, a series of scenario calculations shows that there are invariants, most important: the duration of the early convection phase with high mass transfer rates.

Simulation of Geomechanical Reservoir Behavior during SAGD Process Using COMSOL Multiphysics®

[1]University of Calgary, Calgary, AB, Canada

THM (Thermo-Hydro-Mechanical) behavior of the reservoir during SAGD (Steam-Assistant-Gravity-Drainage) was studied through a proper constitutive modeling of the porous media. Specifically, a generalized density-stress-fabric dependent elasto-plastic model with stress-dilatancy and plastic damage as main ingredients was implemented into COMSOL Multiphysics®, to model geomechanical behavior during ...

COMSOL Multiphysics® software was used to model radial source flow in two dimensional homogeneous porous media. Two-Phase Darcy's Law (tpdl) is used to model miscible viscous fingering. Fingering patterns obtained on using different mesh are discussed. Evolution from 'flowers' to 'branches' is observed in the fingering patterns. Stable displacement is generated even in the presence of unstable ...

Simulation of a Supercritical Fluid Extraction Process Using COMSOL Multiphysics® Software

B. Suryawansi [1], B. Mohanty [1],
[1] Indian Institute of Technology Roorkee, Uttarakhand, India.

In the present work, COMSOL Multiphysics® software was used to solve a mass transfer based mathematical model (Stastova et al., 1996) which is a modified form of Sovova H.,1994 model. The modification has been brought about by introducing the term ‘Grinding efficiency’ in the model and the results of the this model has been compared with the theoretical results obtained by Duba and Fiori, 2015 ...

Pore-Level Bénard–Marangoni Convection in Microgravity

P. Mohammadmoradi [1], A. Kantzas [1],
[1] University of Calgary, Calgary, AB, Canada

Pore-level displacement of heavy-oil during thermal operations such as SAGD and CSS is a complex multi-scale phenomenon. As gravity drainage is the main depletion mechanism within the intergranular pore space, the surface tension-related phenomena are dominant in intra-granular micro-pores. Here, a multidisciplinary study is conducted to investigate the effect of temperature on pore-level ...

One of the most important criteria for evaluating chemical enhanced oil recovery (EOR) processes that use polymers is its rheological behaviour which in turn account for other physical effects of adsorption and resistance factors during polymer-rock interactions. However, complete knowledge of behaviour of polymer solution in porous media has not yet been fully gained. A computational fluid ...
