The understanding of the distribution of electrostatic forces at the nanoscale is of fundamental importance for the development of nanotechnology. In this work, in order to quantify the EFM cantilever/tip-sample interaction, we present a 3D static Finite Element Analysis of the electromechanical interaction between conductive probes and samples, using COMSOL Multiphysics. The simulation ...

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.

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.

The control of the flux within continuous casting systems used in the metallurgical field can be obtained through the application of electromagnetic. The model here has been solved through a linear time-harmonic solver. The results of the electromagnetic model have then been applied to the fluid-mechanics model through volume Lorentz forces.

This paper presents a two dimensional model of a Preferential Oxidation Reactor. The main aim of the mathematical model was to investigate the process performance of the reactor by parametric analysis. Temperature and concentration profiles along the length of the reactor were evaluated in order to enhance optimization and control of the PROX unit.

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 ...

Heat and mass transfer can be analyzed for conditions that may limit shelf-life. With this target, the purpose of the present work is the development of a general model which is applicable to a large variety of packaging configurations, food products and environmental conditions. To this end, COMSOL Multiphysics is exploited in a full 3D geometry.

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 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 ...
