We present a full modal -analysis of optical and acoustic properties based on two-dimensional finite-element method (2D-FEM) for Brillouin Gain spectrum (BGS) determination in optical fibers with COMSOL. This model enables us to predict precisely the BGS of any kind of silica fiber ... 詳細を見る

Energy performances and building energy quality can be achieved by high performance envelopes. In this paper the thermal performance of a naturally ventilated façade, applied to a traditional wall, widely used in existing buildings, was investigated by a transient simulation. A ... 詳細を見る

This paper presents an optimized combination of artificial diffusion techniques to stabilize a drift dominated streamer discharge model which includes COMSOL Multiphysics’ Transport of Diluted Species modules for positive ion, negative ion, and electron charge densities, coupled through ... 詳細を見る

Flow electrolysers find several applications in industry. They are used for production of metals and synthesis of chemicals, gases. Cleaning and preservation of old artifacts, electrolytic refining of metals, electrolytic winning of metals, alkaline water electrolysis, anodization, ... 詳細を見る

Using COMSOL Multiphysics, a finite element model is introduced in this paper to describe the couplings between the welding arc and the weld pool dynamic in pulsed gas tungsten arc welding. The cathode, arc-plasma and melting anode regions are taken into account. The unified time ... 詳細を見る

Despite its real advantages compare to seeded sublimation growth, SiC solution growth has never given convincing results. The difficulty of stabilizing the growth front, and thus avoiding any polycrystal formation results from a poor description and understanding of the coupled phenomena ... 詳細を見る

Polymer electrolyte membrane (PEM) fuel cells have significant potential as a source of clean, efficient energy production. This study presents a three-dimensional, non-isothermal, fully-coupled model of a PEM fuel cell with printed circuit board current collectors. The effect of the ... 詳細を見る

We use COMSOL Multiphysics to model a gas bubble expansion in a viscous liquid initially at rest, a very common system for lightweight foamed materials from metal production and polymer processing. Modelling and simulation of foam processing during the production step involves many ... 詳細を見る

This paper presents model development and simulation results for a microdroplet generator capable of internally measuring the volume of dispensed droplets. The system’s integrated sensing is enabled by storing compressible gas adjacent to the dispenser’s liquid reservoir. During ... 詳細を見る

With the advancement of medical devices and implants, many now require more advanced nonlinear, hyper-elastic materials such as elastomers to be extensively utilized in the body. This combined with the need to allow for considerably different, varying and graduated material responses ... 詳細を見る
