New geothermal energy sources hold promise for the future. Deep submarine geothermal energy related to hydrothermal vents is emerging in many places along the oceanic spreading centers. Shallow submarine geothermal systems are found near to continental platforms. We present the initial development of mathematical models to simulate the energy transport in submarine systems. A model for the ...

Numerical Modelling of Electrophoresis Applied to Restoration of Archaeological Organic Materials

Restoration of archaeological materials from oceans is a major activity of Arc’ Antique. Organic materials such as wood, tissues, leathers, papers and ceramics found in sea water are always impregnated with salts. Rinsing such archaeological objects with pure water to extract the salts takes too long, so electrophoresis was used to improve the salt extraction. The objective of this ...

Design of Novel Recirculation System for Slow Reacting Assays in Microfluidic Domain

N.N. Sharma, and A. Tekawade
Mechanical Engineering Group, Birla Institute of Technology & Science, Pilani, Rajasthan, India

A simple design for a microfluidic flow system for use in mixing or reacting assays with limited sample availability has been proposed and analyzed using COMSOL\'s multiphysics simulation package. The design is based on differential electroosmotic flow concept which has facilitated a number of interesting flow phenomena in micro-domains. For an average potential drop of about 86 kV/m in the ...

Numerical Simulation of a Joule Heating Problem

S.M.F. Garcia[1], and P. Seshaiyer[2]
[1]U.S. Naval Academy, Annapolis, MD, USA
[2]George Mason University, Fairfax, VA, USA

In this work we consider a 1-D mathematical model that describes a heating problem combined with electrical current flows in a body which may undergo a phase change as a result of the heat generated by the current, so-called Joule heating. The model consists of a system of nonlinear partial differential equations with quadratic growth in the gradient. Joule heating is generated by the resistance ...

Expanding Your Materials Horizons

R.W. Pryor
Pryor Knowledge Systems, Inc., Bloomfield Hills, MI, USA

The concept of virtual prototyping can be found linked to many different keywords in the literature: modeling, look-ahead problem solving, etc. This poster paper briefly discusses the potential real benefits that can be realized through pre-build cost savings, minimization of the number of prototype builds, and post-build problem avoidance for physical prototypes and production products. Relative ...

Solving Two-scale Transport Laws During Frying of Foods Using COMSOL Multiphysics

J. Maneerote, and P.S. Takhar
International Center for Food Industry Excellence Texas Tech University, Lubbock, TX, USA

Microscale comprised of the scale of food biopolymers at which biochemical reactions and textural changes take place, and the macroscale was the scale of interaction of polymers with surrounding water, vapor and oil phases. Numerous novel equations such as generalized Darcy’s law based fluid transport equations for various phases; near-equilibrium equation governing phase change from liquid ...

Stress Analysis of an Electromagnetic Horn

B. Lepers
IPHC
Université de Strasbourg
Strasbourg, France

An electromagnetic horn is a device used in particle physics to produce a strong pulsed toroidal magnetic field and to focus charged particles toward a detector. A multiphysics analysis is performed to assess the stress level inside the horn structure. In steady state regime, the horn is submitted to a thermal static stress due to thermal dilatation. Then, every 80 ms a strong magnetic field ...

Multiphysics Simulation of an Anode-supported Micro-tubular Solid Oxide Fuel Cell (SOFC)

G. Ganzer, W. Beckert, T. Pfeifer, and A. Michaelis
Fraunhofer IKTS
Dresden, Germany

The high thermal stability and fast start-up behavior make micro-tubular solid oxide fuel cells (SOFCs) a promising alternative for small-scale, mobile power devices in the range of some Watts. To understand the transport phenomena inside a single micro-tubular SOFC, a 2-D, axi-symmetric, non-isothermal model, performed in COMSOL Multiphysics® 4.2, has been developed. Due to long current path ...
