One of the methods to recover oil from medium and low viscosity in complex reservoirs uses air injection leading to oil combustion. In this case the oxygen in the air burns the heavier components of the oil, generating a heat wave leading to vaporization of lighter components. In this work, we consider a simple model for air injection in light oil reservoir containing only one component in dry ...

Web Based Laboratories for Teaching Electromagnetics for TEMPUS eLab Project

[1]Electrical Engineering Department, The British University in Egypt (BUE), El Sherouk City, Egypt

This paper presents a successful step towards the development of a “web-based laboratory” for teaching basic, and even advanced, electromagnetic concepts. The main idea is to develop a reusable model for the student to be used exactly as a hardware experiment in a physical laboratory, where he/she can change some of the experiment\'s physical parameters and get corresponding results. The two ...

Fuel cells are devices that convert chemical energy of a fuel into electrical energy through electrochemical processes. One of the types of fuel cell is the Solid Oxide Fuel Cell (SOFC) that uses solid ceramics for electrolytes. Numerical simulation involves constructing a mathematical model of the SOFC and use of specifically designed software programs that allows the user to manipulate the ...

3D Simulation of Air-Glass Heat Exchange in a Set of Vials

[1]Marchesini Group, Pianoro, Italy

In this model a three-dimensional heat transfer analysis was performed by using COMSOL Multiphysics\' Heat Transfer Module. The model is about the heating of a set of vials (Figure 1) in a current of hot air in the laminar regime. We used time dependent studies to predict the thermal behavior of the glass and to estimate the temperatures in the various points of the bottles at various times. ...

Modeling Large-Scale Mine Dewatering by Using Subsurface Flow Module in COMSOL Multiphysics

Groundwater is a key factor affecting mine operations worldwide. On one hand, both underground and open pit mines need to pump out groundwater in order to proceed with mineral extraction and increase the stability of rock slopes. On the other hand, groundwater abstractions can produce undesired environmental and social impacts, which should be anticipated in the environmental impact assessments ...

Analysis of Electroosmotic Flow of Power-law Fluids in a Microchannel(1D)

[1]IIT Kharagpur, Kharagpur, West Bengal, India

Electroosmotic flow of power-law fluids in a slit channel(1D) is analyzed. The governing equations are the Poisson–Boltzmann equation, the Cauchy momentum equation, Generalized Smoluchowski equation and the continuity equation are used to get shear stress, dynamic viscosity, and velocity distribution. Simulations are performed to examine the effects of ?H, flow behavior index, double layer ...

A 3D model was developed using COMSOL Multiphysics® to study the flow dynamics of the water inside the geometry of the [13N] Ammonia target for medical application . The image attached shows a 3D model of the target. A significant improvement was noted after modifying the geometry as suggested by the model and delivery time of radioactive solution was dramatically reduced. Water and aluminum ...

[1]Imperial College London, London, United Kingdom

Solid Oxide Fuel Cells (SOFC) and Li-ion batteries (LIB) are electrochemical devices where performance is dependent on reactions inside porous electrode microstructures. Here we use tomographic techniques to probe 3D electrode structures (anodes and cathodes) at micro-nanometer length scales. Subsequently, micro/nano structural changes in electrodes are characterized and quantified. Utilizing ...

[1]University of Málaga, Málaga, Spain

In this work, we study the design of a new integrated system for Solar Water Heating that combines the solar thermal energy collection (primary circuit) with the heat storage (secondary circuit) into the same device. We have performed different finite element method simulations using COMSOL Multiphysics®, for solving the equations of heat transfer (conduction and convection) and those of fluid ...
