This work presents a different use of COMSOL as an integrated component of a computational tool framework used to automate designs creation. CNS-Burst is a computational synthesis method that has been implemented with the aim of automatically generating solutions to an assigned design task. COMSOL is integrated in the method and used to evaluate the performance of the design solutions found. ...

A bidimensional and pseudo homogenous model was proposed for the study of mass transfer in the bioadsorption process of chromium VI in the S-layer of immobilized Bacillus sphaericus in a packed column. The implementation of such a model in COMSOL Multiphysics will be explained in detail and the final results presented. These include chromium concentration profiles along the column and its ...

Analysis and optimization of air flow distribution inside drying kiln systems contribute to the improvement of the final product quality. The present study reports on the threedimensional numerical solution of air flow within a drying kiln enclosure. The air flow field is examined in different configurations and operation conditions. Depending on the off/on switched fans, we obtain various air ...

Piezoresistive pressure sensors have received much attention over the years because of low cost, simple measurement techniques, etc. There is a challenge in design with respect to appropriate positioning, shape and temperature compensation. Different models of piezoresistive pressure sensors are proposed to enhance its sensitivity in terms of output voltage. This paper aims in sensitivity ...

In the core of Chemical Engineering is the reactor design that includes most of all scientific disciplines. The reactors, in general, are treated ideally. Unfortunately, it is observed in the real world a very different behavior from that expected. Thus, to characterize nonideal reactors is used, among others, residence time distribution function E(t). The aim of this present work is to ...

The feasibility of water cooling is investigated for a solid target which is integrated as the inner conductor in a magnetic horn for secondary particle focusing (pi; K) as used in conventional neutrino beam accelerator experiment. A simple axi-symmetric thermal model calculated in COMSOL is used to obtain the temperature distribution inside the target for different values of h; power beam and ...

In this work, a MEMS low-g accelerometer with three sensitive directions is designed for health monitoring applications. The accelerometer may have different sensitivity in different axes. The proof-mass of the device is suspended by four serpentine springs, and the comb drive structure is used to form the differential capacitor to measure the displacement of the proof-mass. The structure has an ...

In this work, time dependent thermal analyses, performed on the 3D FE model of a multilevel Lab on Chip (LOC) platform are executed in order to gain insight into the temperature distribution within the device. By means of the COMSOL Multiphysics CAD import module, an extremely close 3D reproduction of the actual device, allowing to probe temperatures in those regions where an experimental ...

This paper describes the numerical modeling of a key material-stability issue within the realm of Molten Carbonate Fuel Cells (MCFC). The model describes the morphological and attending electrocatalytic evolution of porous NiO electrodes and is apt to predict electrochemical observables that can be recorded during Fuel Cell operation. The model has been validated with original experimental data ...

In an earlier work we developed a finite element bidomain model of an aplysia abdominal ganglion in order to estimate the sensitivity of this contrast mechanism to changes in cell membrane conductance occurring during a gill-withdrawal reflex. We used our model to determine both current density and magnetic potential distributions within a sample chamber containing an isolated ganglion when it ...
