Introduction Fluid flow patterns in research or process-scale equipment where a fluid is contained between concentric rotating cylinders in the absence of bulk axial flow has received notable attention in the field of fluid mechanics. Annular flows occur in many practical applications, such as in the production of oil and gas, fluid viscometers, centrifugally-driven separation processes, ...

At the forefront of a new generation of sensors graphene and graphene composite materials are intensively studied for medical and biosensing applications. The outstanding electrical, mechanical and quantum properties of graphene make them a promising material solution to overlap the existing gap between biological and non-biological systems into a continuum like-viscoelastic integrated model. ...

A generalized model to predict dynamic crack propagation in fiber composite structures is proposed. The proposed approach is based on a generalized formulation based on the Fracture Mechanics approach and Moving mesh methodology. Consistently to the Fracture Mechanics, the crack propagation depends from the energy release rate and its mode components, which are calculated by means of the ...
Multiphysics Simulation of Thermoelectric Systems - Modeling of Peltier-Cooling and Thermoelectric Generation
Fraunhofer-Institute for Physical Measurement-Techniques (IPM), Freiburg, Germany
Electro-thermal interaction is commonly considered only as a matter of joule heating. In addition, the Seebeck-, Peltier- and Thompson-Effects are significant in materials with high thermoelectric figure of merit Z. These thermoelectric materials have a high Seebeck-coefficient α, a good electric conductivity σ, and a poor thermal conductivity λ. They have widespread areas of ...

The Electrical Double Layer (EDL) plays a major role in understanding the interface between a charged surface (e.g. an implant) and ionic liquids (e.g. body fluids). The three classical models of the EDL (Helmholtz, Gouy, and Chapman-Stern) are numerically solved for a flat surface electrode in the 3D Electrostatics application mode of COMSOL Multiphysics® 3.5a. The values of the electric ...

In the paper will be presented the construction of passive magnetic suspension with superconductors. The system of magnetic suspension was designed for GBRIEL project. There is presented numerical test bench of passive magnetic suspension with superconductor. This kind of suspension was selected for generation of magnetic levitation forces in a sledge of take-off and landing system of an ...

This session is devoted to phase change modeling in heat transfer simulations. The great interest in phase change comes from the outstanding thermal performance that it enables in particular for cooling or thermal protection applications. Alternatively, phase change can induce most of the energy cost in drying or cooking applications. In all of these cases, a thermal analysis is required to ...

In this paper, a model for numerically obtaining lamb wave modes and dispersion curves in plates is presented. It is shown that COMSOL Multiphysics can be employed to simulate the behavior of guided waves in dispersive plates, which is useful for NDE applications. A two dimensional steel plate (4x0.1 meters) is excited with a space-time impact point source. To model the point source, we use ...

In microwave heating applications, the energy is introduced directly into the volume of the material and as consequence the quality of the process is highly dependent on the uniformity of the electromagnetic field distribution along it. That is, the non uniformity of the heating is a potential problem with serious consequences. Thermal runaway is the most critical, in materials with temperature ...

Surface Plasmons (SP) or Surface Plasmon Polaritons (SPP) are electromagnetic excitations that propagate at the interface between a dielectric and a conductor, and are evanescently confined in the perpendicular direction to the propagation. They arise via coupling of the electromagnetic field to oscillations of the conductor’s electron plasma and are characterized in terms of dispersion and ...
