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 ...

A numerical analysis of the conjugate optical-thermal fields in an amorphous silicon thin film deposited on a glass substrate and irradiated by a moving Gaussian laser source is carried out. The combined optical and thermal models are solved by means of COMSOL Multiphysics. Results are given for continuous and pulsed moving Gaussian heat sources and they are presented as temperature ...

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.

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 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.

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.

An efficient simulation of the inverse extrusion process has been performed through the coupling of three modules in COMSOL Multiphysics: fluid-dynamics, general heat transfer and ALE. The strain, the strain rate, and the stress field can be completely defined after the complete definition of the velocity field of the material under the action of the tool. The definition of the stresses and of ...

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.
