The need for fast, easy and cost-effective analysis of blood samples as well as our understanding of the functionality of cells and neurons are two rather pressing issues in the modern world. Both of these can be addressed by functional lab-on-a-chip systems, which have been designed and optimized for specific analyses. This paper deals with the design of several different systems for cell ...

Additive Layer Manufacturing (ALM) methods, like Electron Beam Sintering (EBS), constitute an interesting process concerning the production of small series and customized products. However, transient effects occur during processing due to the different physical principles of an electron beam (EB). Thus, process knowledge from similar ALM technologies, for instance Selective Laser Melting, can ...
Advanced Modeling of Friction Stir Welding – Improved Material Model for Aluminum Alloys and Modeling of Different Materials with Different Properties by Using the Level Set Method
Wilhelm Gronbach GmbH, Wasserburg a. Inn, Germany
Friction Stir Welding (FSW) has gained much importance throughout the last years. Beside comprehensive experimental work that has been carried out, the simulation of the welding zone is of major interest. Due to the high strains observed within the welding zone, the Eulerian (CFD) approach seems to be the most promising for the prediction of flow around the FSW tool. However, the CFD ...

Surface acoustic wave (SAW) devices based on Rayleigh wave, shear wave, love wave, acoustic plate mode (APM) wave and flexural plate wave have been explored for sensors, actuators and telecommunication applications. An interdigital transducer (IDT) is a metallic comb-like structure fabricated over piezoelectric substrate. SAWs are generated over the substrate by applying electrical signal to the ...

Glass containing nanoparticles is a promising material for various photonic applications due to the unique optical properties mainly resulting from the strong surface plasmon resonance (SPR) of the silver nanoparticles. The characteristics of the resonance can be modified by varying size, shape and concentration of the particles. A finite element method (FEM) implemented in the software COMSOL ...

In this paper, we discuss a simplified finite element method simulation of surface acoustic wave (SAW) delay line hydrogen sensor using COMSOL Multiphysics. A delay line SAW sensor consists of a transmitting interdigital transducer (IDT) and a receiving IDT separated by a few wavelengths. In this work, the number of degrees of freedom to solve for the SAW delay line sensor model ...

This paper presents the mathematical modeling for the analysis of the magnetostrictive materials, which describes the behaviour of the magneto-mechanical coupling in a rod of magnetostrictive material and capturing it in COMSOL® to produce a predictive and detailed analysis. A simulation of the behaviour under harmonic excitation is done in this work.

Temperature and residual moisture content of a stationary Textile in a home tumble dryer are simulated in a 2D model with COMSOL Multiphysics. Moisture migration to the textile surface is modeled in the form of capillary flow and vapor diffusion along with heat transfer in the form of conduction and energy lost due to phase change (evaporation). The drying air energy, mass and momentum transport ...
