[1]Aalto University, Greater Helsinki, Finland
[2]University Of Helsinki, Helsinki, Finland

There is a great need for an effective drug treatment of the posterior eye, as the major reason for visual disability in industrial countries is Age-related Macular Degeneration (AMD). In USA alone, there are almost 2 million people affected by AMD [1]. A virtual pharmacokinetic 3D model ... Read More

Thermal Study of Valve Regulated Lead Acid Batteries and Electronics Chamber Used in Stand-Alone Street Lighting Applications new

D. Groulx[1], J. Skaalum[1], T. Jamieson[1]
[1]Mechanical Engineering, Dalhousie University, Halifax, NS, Canada

This paper presents a study on the heat generation of Valve-Regulated Lead Acid (VRLA) batteries used in off-grid streetlighting applications from PoleCo, a Halifax based company. One goal of the project was to produce validated COMSOL® models of the enclosure that holds these VRLA ... Read More

Magneto-Hydrodynamic Numerical Study of DC Electromagnetic Pump for Liquid Metal

A. Daoud, and N. Kandev
Institut de recherche d'Hydro-Quebec (LTE), Shawinigan, Quebec, Canada

The electromagnetic pumping (EMP) of electrically-conducting fluid is of growing interest for many industrial applications requiring precise flow control, enabling stopping or reversing flow direction without any moving parts or mechanical devices. Presented in this work are  ... Read More

Simulating A Fan For Industrial Ventilation

G. Argentini
Riello Burners, Italy

This work talks on simulation of a ventilating structure for an industrial burner. The mathematical model is based on the frozen-rotor technique, and the numerical simulation is used for resolution of fluid dynamics equations for the air flow into the rotating wheel and into the static ...

Hydrodynamics of Lake Victoria: Vertically Integrated Flow Models in COMSOL Multiphysics® Software new

S. Paul[1], R. Thunvik[1], D. D. Walakira[2], J. Mango[2], J. Oppelstrup[3], R. Wait[4]
[1]The Royal Institute of Technology, Stockholm, Sweden
[2]Makerere University, Kampala, Uganda
[3]COMSOL AB, Stockholm, Sweden
[4]Uppsala University, Uppsala, Sweden

Lake Victoria is the largest tropical lake in the world and is very important for environment and economy in East Africa. The hydrodynamic processes in the shallow (40-80 m deep) water system are unique due to its location at the equator which makes Coriolis effects noticeable also for ... Read More

Air Bubbles Motion Through Fresh Concrete During Concreting Process

E. Chuta [1], J. Jeong [2],
[1] Université Paris-Est, IRC-ESTP, Cachan, France
[2] IRC-ESTP, Cachan, France

Over the last years, the concrete technology has progressed in order to improve the quality of its use and mechanical performances. Despite the technical development known in the context of concrete, the esthetic aspect remains weakly treated. Among the esthetic problems, there is the ... Read More

Sample Preconcentration in Channels with Nonuniform Surface Charge and Thick Electric Double Layers

A. Eden [1], C. McCallum [1], B. Storey [2], C. D. Meinhart [1], S. Pennathur [1],
[1] University of California Santa Barbara, Santa Barbara, CA, USA
[2] Olin College, Needham, MA, USA

We present a novel method for concentrating and focusing small analytes by taking advantage of the nonuniform ion distributions produced by thick electric double layers (EDLs) in nanochannels with heterogeneous surface charge. Specifically, we apply a voltage bias to a gate electrode ... Read More

Heat Transfer Modeling for Thermal Stimulation of Near Wellbore Using COMSOL Multiphysics®

M. Mohammed [1],
[1] Freiberg University of Mining and Technology, Sachsen, Germany

The performance of the oil reservoir is decisively determined by the hydraulic permeability of the rock and the possible flow paths. During the production phase, the petrophysical properties of the rock may deteriorate due to highly viscous oil deposits, especially in the near of the ... Read More

Optimizing Design of Soil Mixing Equipment through COMSOL Multiphysics® Simulations

[2]Alpine Sales & Rental Corp./Alpine Equipment LLC, State College, PA, USA
[3]Department of Energy and Mineral Engineering, The Pennsylvania State University, University Park, PA, USA

Soil mixers are widely used to mix biochemical agents and additives to remediate contaminated soils or drill cuttings and sludges. Through COMSOL Multiphysics simulations, this paper aims to evaluate the effect of geometric configuration of the blades and rotational speed on the mixing ... Read More

COMSOL Multiphysics for Efficient Solution of a Transient Reaction-Diffusion System with Fast Reaction

M.K. Gobbert[1], A. Churchill[1], G. Wang[1], and T.I. Seidman[1]
[1]Department of Mathematics and Statistics, University of Maryland, Baltimore County, Baltimore, Maryland, USA

A reaction between chemical species is modeled by a particular reaction pathway, in which one reaction is very fast relative to the other one. The diffusion controlled reactions of these species together with a reaction intermediate are described by a system of three transient reaction ... Read More
