Damping is the liminting factor for the reachable maximum deflection. Thus, it is a very important issue for resonant microsystems. In this paper, we present a damping model for out-of-plane comb driven resonant micromirrors. The basic concept of this model is to attribute viscous ... En savoir plus

Black-oil simulators are commonly used in petroleum reservoir engineering for the prediction of oil production, especially during the earlier stages of oil-field exploitation, while also serving to guide pressure maintenance strategies in the longer term. Such models account for fluid ... En savoir plus

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 ... En savoir plus

The aim of the present work is to implement in COMSOL Multiphysics a multiphase fluid flow model in porous media, also known in the oil reservoir engineering literature as a black oil model, using a standard finite element approach. In particular, we are interested to apply this model ... En savoir plus

Solar systems are used around the world, especially in sunny and dry regions, to convert radiation energy from the sun into electricity or heat. Soiling, as dust deposition onto surfaces is commonly called, hinders this conversion of the solar energy by blocking of the incidenting light. ... En savoir plus

Phosphoric acid doped polybenzimidazole (PBI) membranes are commonly used in today’s high-temperature polymer-electrolyte-membrane (HTPEM) fuel cell technology. COMSOL Multiphysics is used to model and simulate the three-dimensional, single-phase, non-isothermal overall cell behaviour ... En savoir plus

The Manufacturing Technology Centre (MTC) is home to the UK’s National Centre for Net Shape and Additive Manufacturing, offering integrated solutions to potential end users, supply chain companies or equipment providers using a three phase approach: discovery, demonstration and pilot ...

In this work, we design a type of meta-prism which can provide high-efficiency coupling between free space and optical waveguides at infrared frequencies. The meta-prism is composed of an ABA multilayer structure with a fixed total thickness. By varying the filling ratio of the ... En savoir plus

As a key component of MEMS, microprocessor with high computing performances is facing with severe thermal challenge due to the increasing power density, miniaturization as well as higher operating temperature requirements, and thermal management in corresponding fields has become one of ...
