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 ...

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 ...

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 ...

Descemet membrane detachment (DMD) happen when the aqueous humour (AH) in the aqueous chamber flow into the descrement membrance (DM) space through a break and separate the membrane from the stroma. This often happen after the cataract surgery. The fluid is driven by the buoyancy force that generated by to the existing of temperature different between the cornea and the pupil. COMSOL ...

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. ...

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 ...

Jet Electrochemical Machining (Jet-ECM) is an unconventional procedure for micromachining. Based on localized anodic dissolution three-dimensional geometries and microstructured surfaces can be manufactured using Jet-ECM. COMSOL Multiphysics is used at Chemnitz UT to simulate the electric current density in the jet and the dissolution process. A mesh displacement dependent on the normal current ...

The last glacial cycle in the Northern Hemisphere started approximately 120,000 year ago. During that cycle, Southern Ontario was buried under a continental ice cap, with a maximum thickness of up to 3km. The ice cap retreated approximately 10,000 years ago. The COMSOL Multiphysics code is used to model the physical processes of the impact of past glaciations on the evolution of hydraulic system ...
Finite Element Analysis of an Enzymatic Biofuel Cell: The Orientations of a chip inside a blood artery

Output performance of an implantable enzymatic biofuel cell (EBFC) with three- dimensional highly dense micro-electrode arrays has been simulated with a finite element analysis approach. The purpose of this research is to optimize the orientation of this EBFC chip inside a blood artery such that the mass transport of glucose around all the micro-electrodes can be improved and hence output ...
