Fusion is a form of nuclear energy which has impressive advantages from the point of view of fuel reserves, environmental impact and safety. If successful, fusion energy would ensure a safe, resource conserving, environmentally friendly power supply for future generations. In a world wide cooperation to achieve this goal, seven parties including Europe, Japan, Russia, USA, China, South-Korea and ...

We present a study of an optofluidic biosensor. The sensor operates in a transmission mode wherein detection is based on a shift in the transmission spectrum caused by the contrast in refractive index between the carrier fluid and the target biomaterial. We study the behavior of the sensor using 2D full-wave electromagnetic analysis, and perform parametric studies of sensitivity as a function ...

Electrochemical Machining with a closed electrolytic free jet is a special procedure to generate complex micro structures by help of anodic dissolution. The work piece shape is fabricated by supplying an electrolytic current through an electrolyte jet ejected from a small nozzle. In this study COMSOL Multiphysics is used to simulate the electric current density in the jet and the dissolution ...

The paper attempts to give a contribution to the dynamic analysis of musical instruments. A multidisciplinary approach oriented to the study of mechanical, structural, vibratory and acoustical phenomena related to stringed instruments is discussed. The case study focused in this paper concerns the violins family: the geometry and the vibratory propagation of this instrument is very complicated ...

In volcanic areas, the presence of heterogeneous materials and high temperatures affect the rheological behaviour of the Earth's crust that calls for considering the anelastic properties of the medium surrounding the magmatic sources. A thermo-mechanical numerical model is performed for evaluating the temperature dependency of the elasto-plastic solution. Both temperature distributions and ...

In this study, a 2-D model has been built using COMSOL Multiphysics® to analyze a triple coupled physics problem involving simultaneous gas diffusion, heat transfer, and structural mechanics in a pipe due to the flow of high-pressure carbon dioxide. The problem geometry and boundary conditions were based on the analysis by Rambert et al. who have published the most advanced modeling work in ...

This document describes a method for maintaining the long-term calibration of a full color direct thermal printer. An essential component of the system is a thermal model created using COMSOL Multiphysics that allows fitting of color data recorded at different temperatures and exposure times to model results for the same conditions. The fitted results reveal the depth and thickness of color dye ...

This study aims to numerically investigate on a passive solar system for indoor heating called as \"Trombe wall\". The transient buoyancy driven flow characterizing that system and the thermal distribution are solved by numerically integrating the governing equations in COMSOL Multiphysics environment. Simulations are carried-out for a time range corresponding to 12 days. The results are ...
