Opalinus clay is currently being proposed as a potential host rock for radioactive waste repository in deep geological formation. It is then important for performance assessments to understand the transport properties of such rocks. Clay materials are characterized by low hydraulic conductivities and diffusion is assumed to be the main transport mechanism. The studied rock is a complex assembly ...

Singlet oxygen (1O2) is the major cytotoxic agent during type-II photodynamic therapy (PDT). The production of 1O2involves the complex reactions among cancer agent, oxygen molecule, and treatment laser light. The light propagation in tumor tissue is described by the diffusion equation. In this work, an optimization routine is developed to fit the [1O2]rx profile to the simulated necrosis ...

Magnetorheological Elastomers (MREs) are a composite that consist of magnetic micrometer sized particles suspended within rubber matrix filler. By placing this material within an external magnetic field during the rubber curing process, the poles of the particles are forced to align and form chains of particles within the matrix. These chains cause the MRE to change its stiffness properties when ...
COMSOL Grab Bag: How to Use a Versatile CFD Code to Model Interesting Problems from Cryogenic Storage to Biofuel Production
Senior Research Engineer,
NASA Glenn Research Center, Cleveland, OH, USA
Emily Nelson received her PhD in Mechanical Engineering from the University of California at Berkeley. She is a senior research engineer at NASA Glenn Research Center and specializes in the formulation and solution of problems in microgravity science, multiphase flow, porous media, risk analysis, and gravitational biology. This leads her to fundamental and applied approaches on a range of issues ...

A new type of radiator with a package of combs, to gain a larger area for heat exchange, instead of trapezoidal convector plates, is investigated. The main aim is to find the optimal comb diameter. To solve this problem, CFD (computational fluid dynamics) with COMSOL Multiphysics is used. A chart showing radiator power was produced, which includes radiator power for different temperatures and ...

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 ...

We propose the study of an electronic sensor allowing the collection of sprays in free space. The detector consists of three elements: a photodiode situated in the center of the structure to which is applied a bias voltage, an aluminum ring which referenced to a voltage higher than that of the photodiode and an insulating material disk (polyvinyl chloride). The total size of the structure is ...

The paper presents the results of the experiment consisting in determination of the influence of the magnetic field on deformations of the stator and the rotor of the DC motor. The numerical model of the motor for the frameless DC machine of the G series has been elaborated. Real material properties and the phenomenon of the magnetic circuit saturation have been taken into consideration. The ...
Modeling of Nonlinear and Non-stationary Multi-vortex Behavior of Electronic Crystal in Restricted Gemoetries of Nano Junctions
T. Yi, Y. Luo, and S. Brazovskii
Electronic Crystals are common forms of organization of charge in solids. They appear widely from nano-structure semiconductors to synthetic organic conductors. Charge density wave, the best treated kind of electronic crystal, can readjust its elementary units by creation of topological defect or vortex. Experimental accesses to these phenomena came from nano-junctions, scanning tunneling ...

The paper aims to clarify some aspects of the gases hydro-dynamics within the twisted conduct of heat accumulation stoves (ceramic-refractory stoves) downstream the combustion chamber. Both Comsol laminar and k-e turbulent models have been used in case of straight and curved pipes with circular, square and rectangular cross-sections, at different Reynolds numbers, in case of smooth wall (Comsol ...
