A theoretical investigation of thermo-optic effect in Silicon-on-Insulator (SOI) rib waveguides and waveguide arrays by means of the Finite Element Method (FEM) has been carried out. Both static and dynamic analyses have been performed.

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.

Mathematical modelling of a catalytic plate reactor for methane steam reforming with COMSOL Multiphysics was carried out. The model reactor includes three channels where methane combustion occurs on the plates bordering the inner side of the outermost channels, whereas methane steam reforming takes place on the plates bordering the central channel.

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 ...

In this paper we study the natural convection for Dual In-Line Memory Module (DIMM) systems. Numerical models are developed using COMSOL Multiphysics. The results, obtained for imposed ambient temperature and operative conditions (power supplied to the CPUs) were produced and complex fluid motion field could be detected.

In the present paper we report the results obtained applying COMSOL Multiphysics to the numerical simulation of Cyclic Voltammetries (CV’s) at microelecrodes arrays. CV’s at inlaid micro disk electrode arrays have been simulated showing how the electrochemical response is affected by geometrical parameters such as the electrode radius and the distance among the electrode canters.
