A 2D isothermal axisymmetric model of an anode-supported Solid Oxide Fuel Cell (SOFC) has been developed. Also a parametric analysis to find the effect of important parameters on the cell performance has been done. This simulation has been carried out at 1 atm and 1073 K. The PEN materials are traditional ones: Ni-YSZ/YSZ/LSM-YSZ as anode, electrolyte and cathode respectively.The developed model ...

In this model a three-dimensional heat transfer analysis was performed by using COMSOL Multiphysics\' Heat Transfer Module. The model is about the heating of a set of vials (Figure 1) in a current of hot air in the laminar regime. We used time dependent studies to predict the thermal behavior of the glass and to estimate the temperatures in the various points of the bottles at various times. ...

The paper presents recent results concerning the experimental mechanical characterization, the numerical modeling and the design of micro-needles used in the construction of probe heads for wafer testing. A fully coupled electro-thermal model was created using COMSOL and combined to a research-oriented thermo-mechanical Finite Element (FE) code in order to accurately reproduce the micro-needle ...

It is now a well known that the next generation devices in many fields of the semiconductor industry will be based on 3D architectures. In this framework, low thermal budget annealing technological solutions are required. For many applications, either in the field of sensors, microprocessors or high density memories, the Laser Thermal Annealing (LTA), an ultrafast and low thermal budget process, ...

We study the topography influence of levees on the electric resistivity signal obtained with the Radio-Magnetotelluric method. Field measurements have been modeled with COMSOL, using the AC/DC and RF Modules. A levee situated in Orléans along the Loire river (France) has been considered in order to design a model tacking account of the skin depth and the incident wavelength, keeping a constant ...

Phreeqc is a program for simulating chemical reactions and 1D transport processes in aqueous systems. Several couplings between conservative transport codes and PHREEQC already exist. The methodology used here is based on the operator splitting concept: the transport of the aqueous components and the chemical reactions are solved in two different steps. The Java interface uses the COMSOL Java ...

This paper presents a numerical study of the deposition of submicron charged spherical particles caused by convection, Brownian and turbulent diffusion in a pipe with a smooth wall and with a cartilaginous ring wall structure (see figure). The model is supposed to describe deposition of charged particles in generation 0 (trachea) of the human lung.The problem is defined by solving the fluid flow ...

Presented work is motivated by pre-realization phase of rock heating experiment in underground, testing properties for cyclic energy storage. Heating unit, installed in large borehole from end of a tunnel, is fixed to the rock face with the geo-polymer. Rest of the borehole is filled with isolation material. We used the Heat Transfer Module and the Structural Mechanics Module in COMSOL for ...
