In a nuclear reactor, the containment is the last barrier for the release of radioactivity during severe accident conditions. Containment material can be concrete or steel or steel-lined concrete. Steel containments have a high load bearing capacity and a high degree of leak tightness at higher pressures. In case of a severe accident, heat can be removed from the containment by a guide panel, ...

Photonic crystals (PhC) are optical nanostructures that are widely known for their strong spatial and temporal confinement of electromagnetic radiation. Here, we study the resonant optical trapping of a single nanoparticle within a hollow circular photonic crystal cavity. The Electromagnetic Waves (emw) interface of COMSOL Multiphysics® was extensively used during the analysis of all our ...
A Research of Electro-thermal Coupling Model for Lithium-ion Battery with Multiphysics in COMSOL Multiphysics®
戴海峰 , 许阳 , 朱建功 ,
A new method is proposed to study battery thermal behavior under nature convection condition, especially focusing on temperature rising and inhomogeneity of battery. Using porous electrode theory, an electrochemical and homogenization heat source thermal coupling model and an electrochemical-distributed heat source thermal coupling model are established. In the meanwhile, to improve inhomogenity ...

Tonal noise from wind turbines can have effects on neighboring residences and its emission can result in strong regulatory penalties that can include the closure of wind farms. The authors present a model of a new broadband damping approach where containers filled with EniDamp™, an Advance Particle Damping (APD) material. The containers, so-called APD pods, are magnetically fixed to wind ...

Laser direct deposition is a process, different from molding or machining, which allows the producing of fully densified and operational components. This technique involves injecting metal powder through a coaxial nozzle into a melt pool obtained by a moving laser beam. The final object is obtained by superimposing the layers created by the process. The roughness of the functional part is ...

The idea of application as a hearing device based on a parasitoid fly, Ormia ochracea has been studied extensively recently. This paper addresses another possible application as an underwater directional sensor. In order to study the feasibility of the application, it is necessary to investigate the feasibility of the underwater application of the directional sensor based on the hearing ...

Electrowetting on Dielectrics (EWOD)systems is widely practiced digital microfluidic technique, used in Lab-on-a-Chip (LoC) system for biomedical application. In EWOD, with applied potential, the droplet minimizes its surface energy by transiting towards the actuated electrode. The problems with EWOD device for biological sample are that it will damage the cells if applied voltage across it ...

This paper reports the design of a piezoelectric energy harvesting micro generator for an energy autonomous tire pressure monitoring wireless sensor node. For our design we use a piezoelectric MEMS generator approach without additional mass. The intrinsic mass of the cantilever is in the microgram region and the resulting acceleration forces are very small. The generator has a triangular ...

Over the last decade, electrowetting-on-dielectric (EWOD) has become one of the most blistering and versatile tool in digital microfluidics. It enables control over fluid shape and flow by electrical signals alone, which is viable by effective utilization of the excess charge accumulation at the interface between the droplet and the dielectric surface, also by polarization of line tension at the ...

The aim of present work is to present and calibrate a new mechanistic model that includes physical and biokinetic processes to reproduce the algae growth in photobioreactor or ponds during long-term scenarios. A COMSOL Multiphysics® model is used to implement the microalgae processes mainly based on River Water Quality Model 1 (RWQM1) (Reichert et al., 2011). The main innovation of the model is ...
