This paper describes an example of full fluid structure interaction. The 2D dynamics of a box-type pile-anchored floating breakwater is solved by means of two models using COMSOL Multiphysics . Simulated wave transmission and vertical displacements of the floating breakwater agree well with physical model results.

This paper deals with the nonlinear magnetic analysis of a 100 Nm, multi-disc, magnetorheological fluid rotary brake or clutch, carried out with COMSOL Multiphysics. Along with the results of the analysis, the paper presents merits and limitations found in the use of the software and introduces current efforts to include in future simulations the thermal and the mechanical responses of the ...

For museums and the like, the indoor climatic conditions should preserve the exhibited works of art and ensure comfort conditions for people visiting or working inside them. The present paper concerns a primary study of the Hall of the Two Hundred of the Old Palace in Florence. General 3D modeling principles were used, which can be applied to many situations where there is interaction ...

3D model analysis of the temperature dynamics during a welding process is presented. Bio-heat equation described laser-tissue interaction in porcine and human eyes, simulating the surgery conditions. The modeled behavior of the superficial cornea temperature was compared with direct measurements performed by an infrared thermo-camera. The results indicated a selective, spatially-confined ...

A two dimensional description of plasma charged sheath and ion extraction, including the complete plasma sheath equation, is proposed and reduced to a system of coupled fields, implemented with use of COMSOL Multiphysics. A separate application of the weak form to the Hamilton-Jacobi and Poisson equations is also described, using five coupled fields.

This research presents a model describing the behavior of fluids during a septic filling processes. Numerical simulations were performed to investigate the laminar flow and rheological behavior of shear thinning and Newtonian fluids in 3-dimensional steady state and time-dependent configurations. The mass and momentum balance equations were solved with the finite element method using ...

In water we can’t see far, because light and electromagnetic waves are absorbed over relatively short distances. In contrast, sound travels very well in water In fact it is well known that marine mammals rely on sound for communication over large distances, and some of them even use sound to locate their target while hunting. In this presentation we provide an overview of the principles of ...

Microcantilevers made of crystal silicon are probably the most diffused type of MEMS because of their simple fabrication and their vast applications. In this presentation we treat the mechanical behaviour of silicon mirocantilevers, and also give an overview of the many application areas that these apply to.

Buffer chemical polishing is a cheap, simple and effective processing technique for single grain high gradient and polycrystalline lower gradient cavities. This paper describes the thermal-fluid finite element model adopted to simulate the process, the experimental flow visualization tests performed to verify the simulation and a novel device fabricated to solve the problem.

In this communication, we deal with the numerical simulation of Voltage Operated ionic Channels (VOC) in Bio-Electronics. Suitable functional iteration techniques for problem decoupling and finite element methods for discretization are proposed and discussed. Model and computational procedures are validated in the simulation of a real-life VOC under several working conditions.
