Modeling Charge/Discharge Heat Generation of Li-ion Cells and Experimental Verification of Temperature Distribution

Tatsuya YAMAUE[1]
[1] Kobelco Research Institute, Inc., Kobe, Hyogo, Japan

Modeling the heat generation and the heat transfer of the electrode of lithium-ion battery are introduced. There are several models, such as an homogeneous heating model and a model considering the current and reaction distribution of electrode. Generally, electrodes have large area and the calculation load of the model becomes high. Therefore, some approximated models are required to analyze ...

Parameter Estimation of Anisotropic Diffusion in Clay with COMSOL Multiphysics® - new

[1]Helmholtz-Zentrum Dresden-Rossendorf, Institute of Resource Ecology, Research Site Leipzig, Leipzig, Germany

Our GeoPET camera is explicitly dedicated for and well capable of 4D monitoring of solute transport in dense geological material, c = c(x,y,z,t) [1-4]. We apply COMSOL Multiphysics® for reproducing our experiments and extracting parameter sets for our 4D problems [5-6]. By aligning simulated results of anisotropic diffusion in clay to our observations we are able to clearly differentiate and ...

The safety assessment of the deep geological repository for nuclear waste of Olkiluoto (Finland) requires the evaluation of the influence of the land uplift (ice withdrawal) in groundwater. With this objective in mind, we have developed a three dimensional reactive transport model of the Olkiluoto, simulating the most relevant deformation zones in a three-dimensional domain. The evolution in ...

2-Dimensional Incompressible and Compressible Mantle Convection - new

Changyeol Lee[1]
[1]Faculty of Earth and Environmental Sciences, Chonnam National University, Gwangju, Republic of Korea

COMSOL Multiphysics® software has been used in computational geodynamics for years. Because very high pressure in the mantle even significantly compressed the mantle up to ~40%, it is crucial to consider the mantle compressibility in computational geodynamics. COMSOL Multiphysics allows consideration of mantle compressibility using the CFD Module and I benchmarked COMSOL Multiphysics using ...

Iberian COMSOL Multiphysics Conference

The Organizing Committee of the Iberian COMSOL Multiphysics Conference 2014

In the conference we bring together a community that is scientifically diverse in an event about the use of COMSOL Multiphysics. Oral and poster presentations highlight achievements in multiphysics modeling and simulations using COMSOL.

Design and Strain Analysis of Artificial Femoral Head and Stem

The majority of elderly patients are subjected to hip bone replacement due to dislocation of bone, mechanical failure and infection. The life time of the implant varies from patient to patient depending on their daily physical activity. Once the implant fails, re-operation of hip bone replacement is performed. In United States, there are approximately 18 revision hip replacements performed for ...

Rotor Modeling at Low Temperature for NMR

N. Luchier [1,2], P. Forestier [1,2], E. Bouleau [1,2]
[1] Univ. Grenoble Alpes, Grenoble, France
[2] CEA, Grenoble, France

Our laboratory is currently leading the design and the manufacture of a novel device that allows NMR spectroscopy to be cooled down to cryogenics temperature (in the 10-100 K range). The system features a sample-holder that rotates at very high frequencies (f >10 kHz). Two aerostatics gas-bearings, allows this sample holder to be suspended in its chamber thanks to a Helium flow. A second Helium ...

Magnetic Prospecting Modeling of Seamount with COMSOL Multiphysics

G. Ha, S.-S. Kim [1]
[1] Chungnam National University, Daejon, Korea

In general, seamount magnetic modeling assumes uniform magnetization for the entire construct. The following geologic obervations are often not considered: 1. The internal structure composed of multiple volcanic layers, and 2. Remanent magnetization gained during the magnetic polarity reversals. In this study, we build synthetic models based on these geological building processes of seamounts. ...

Numerical Simulation of Pulsed TIG Welding Partial and Full Penetration

[1]Ecole Nationale Supérieure de Techniques Avancées, Palaiseau, France
[2]AREVA NP, Centre Technique Soudage, France

In this poster, a numerical model of spot pulsed current TIG welding for partially and fully penetrated weld pools is presented. Heat transfer and fluid flow in the weld pool driven by the combination of electromagnetic force, buoyancy force, surface tension gradient and latent heat are included in our model. A new formulation of the electromagnetic problem is introduced to take into account ...
