Structural, morphological and ground deformation studies suggest that the eastern flank of Mt. Etna (eastern Sicily) is spreading seaward. According to the deep-seated spreading model, both the volcanic edifice and its uppermost basement are spreading eastwards because of magma inflation processes related to a dike complex located at a depth between the summit craters and the Valle del ...

High temperature superconductors (HTS) are promising candidates for electrical power applications. However, the superconductors exhibits energy loss known as AC loss when exposed to time varying external magnetic field and/or transport current. In this paper, AC loss in an elliptical Ag sheathed Bi2223 (HTS) tape is calculated using the time dependent PDE mode of COMSOL Multiphysics. The HTS tape ...

This paper deals with the simulation study using COMSOL on the deformation of drop-within-drop system in a high intensity oscillating electric field. It consists of a composite drop suspended in a continuous phase. This composite drop has a smaller inner drop suspended within the larger outer drop. The outer drop is made up of another immiscible liquid. A high intensity sinusoidally varying axial ...

A three dimensional COMSOL Multiphysics, transient analysis, diffusion model has been adopted to model the transfers of water in the industrial concrete floors. To take into account the different initial saturation levels at the different levels of the slab, the model is divided into three subdomains. The rise of the waterfront is also simulated and the air overpressure thereby developed at the ...

A dual-trap optical tweezers is used for deforming the red blood cell (RBC) in suspension and studying its elasticity. The 3D deformation of the cells was computed with the elastic membrane theory. The calculated deformation can fit to experimental data resulting in cell’s elasticity coefficient. The static approach is valid only for small deformation (5-10%). For a large deformation such as ...

The current paper describes how a properly chosen skew angle can be used to significantly decrease the amplitude of the high and/or low frequency cogging torque components. The approach is further demonstrated with the help of FE results from COMSOL Multiphysics. The numerical analyses incorporates a COMSOL model that is similar to a combination of two examples from the AC/DC Model Library: the ...

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 ...

Technological processes in the engineering practice from point of view of systems and control theory are frequently in the form of distributed parameter systems (DPS). Techniques of FEM based modeling and design of control synthesis methods of DPS which is acceptable for various technological processes, will be demonstrated on modeling and control of temperature fields of the glass melting ...

Enzymatic biofuel cells (EBFCs) are miniature, implantable power sources, which use enzymes as catalysts to perform redox reaction with biological fuels such as glucose. In this study using COMSOL Multiphysics, we use an EBFC chip, having three dimensional, highly dense micro-electrode arrays, fabricated by C-MEMS micro-fabrication techniques. Glucose oxidase (GOx) is immobilized on anodes for ...

In this paper, a Finite Element (FE) and scaled-up experimental modal analysis are employed to estimate the natural frequencies of individual spherical and ellipsoidal cells. It is apparent that the mechanical properties of the living cells and particularly the natural frequencies might be related to the health condition of cells, and therefore a comprehensive analysis is carried out to determine ...
