This work aims at the modelling of a 5 cm^2 Direct Methanol Fuel Cell (DMFC) with mixed serial/parallel serpentine flow fields in terms of current/voltage behavior. One of the main challenge to overcome consists on lowering the so-called methanol cross over from the anode through the polymer membrane to the cathode that is responsible for mixed-potential formation at the cathode where both ...

The direction of the fluid is strongly related to the Reynolds number; as it increases, so does the centrifugal acceleration which tends to push the axial flow towards the outer side of the pipe. Secondary flow appear as 2 or 4 vortical structures after the inflection point. For low Reynolds number, the rotational direction of vortical structures remains unchanged. The core of the vortical ...

INTRODUCTION: Abnormalities in local body surface temperature have been recognized as a sign of disease for centuries, much before humans knew about the cause of ailments or of pain . The idea of this work is to use numerical simulation tools to predict the location, size and metabolism of tumor embedded in any outer body organ of human. Idealized thermal data of an organ, modeled either as a ...

Polymer–metal is a kind of new composite materials rather than traditional metal packaging materials. It has both features of polymer film and sheet metal. However, the polymer film will damage in the sheet metal forming process. Therefore, we try to established a sheet metal forming model with punch and die in the study, based on solid mechanics module of COMSOL Multiphysics® software. We ...

Adequate cooling of beverages is a major issue in planning of several types of events, e.g. poster sessions at conferences. One crucial factor is the time needed to cool beverages from its initial temperature to the desired drinking temperature. We present a way to determine a close approximation for the cooling behavior of three types of commonly used beverage containers using COMSOL ...

Spontaneous emission -- an electron in an excited state of an emitter spontaneously decays to another state with lower energy -- plays an important role in determining the performance of light-emitting diodes, fluorescent dyes, colorants, solar cells, etc. The efficiency of spontaneous emission is determined by the interaction between the emitter and its local electromagnetic environment(1, 2), ...

The results of two thermal response tests recently performed on two vertical borehole heat exchangers (BHEs) are presented. The BHEs have the same cross section and a depth of 100 m and 120 m respectively. The evaluation of the thermal properties of the ground and grout are performed by a finite-element simulation method, developed through the software package COMSOL Multiphysics 3.4.

Fresh fruits and vegetables are gaining importance in the human diet because they contain many beneficial compounds. Among these compounds, phenols are of vital importance due to their antioxidant properties. It is well evident from previous researches that the skin of red grapes is considered a good source of phenols. The aim of this work is to simulate the extraction procedure of phenols in ...

This paper presents a novel methodology towards the design, analysis, and the fabrication process involved in developing a cost effective method to create a piezoelectric actuator by means of the flexoelectric effect. The basic physical equations of the flexoelectric effect and the qualitative analysis of the flexoelectric actuator are done using COMSOL Multiphysics. This effect is used to align ...

We present an implementation of the Structural Mechanics module of COMSOL Multiphysics to model the state of stress associated with the emplacement of large volcanic edifices on the surface of a planet. These finite element models capture two essential physical processes: (1) Elastic flexure of the lithosphere beneath the edifice load, and (2) Pressurization of a magma-filled chamber that serves ...
