Wine quality is strongly dependent on the operation parameters of the production process. In batch or fed batch reactors, the rotating velocity should be carefully controlled to avoid cellular stress and ensure adequate mixing of the mixture. Moreover, precise control of substrates ...

Plasma reactors can be applied to the conversion of waste, biomass and fuels to synthesis gas (mixture of hydrogen and carbon dioxide) with efficiencies as higher as 90-95% and low energy demand, depending on the design optimization. In this work, a multi-step approach was applied to the ... En savoir plus
The paper describes the use of COMSOL Multiphysics to simulate an ECT (Eddy Current Testing) sensor, designed to inspect the elements of the reinforcement of concrete structures. The paper describes the steps for the COMSOL simulation, and analyze the results for three configurations ... En savoir plus
O presente estudo visou a avaliação, por meio do método dos elementos finitos, das tensões geradas em um arco ortodôntico chamado de Arco de Retração Dupla Chave, também conhecido como DKL. Para isso foram modeladas as geometrias do arco DKL, dos bráquets e das coroas dentais, no ... En savoir plus
Este trabalho tem como objetivo o estudo do fenômeno da eletroporação, mais especificamente, a formação de poros nas membranas plasmática e nuclear, a fim de identificar previamente a influência de cada parâmetro ao longo do processo, buscando configurações que proporcionem melhores ...

Dental restorations can be made by different materials bonded together, which grant good mechanical resistance and aesthetic at the same time. In order to evaluate the behavior of dental restorations in the oral environment, a test, called thermocycler, is used, which simulates the ... En savoir plus
The performance of a PEMFC depends on several factors, including the flow inside gas channels. Low gas velocity inside the channel can make water management more difficult, possibly causing water to accumulate and condense in certain regions of the cell. In the present work, COMSOL ...

O objetivo deste trabalho foi modelar a perda de umidade de bananas Caturra com os modelos empíricos e com o software COMSOL Multiphysics, definindo os coeficientes convectivo de transferência de massa e difusivo. O valor obtido para coeficiente de difusão, com base no ajuste matemático ... En savoir plus
The objective of this study is to assess polymeric insulators subjected to polluted environments. The study cases were conducted on polymeric insulators of 500 kV lines. All analyses were carried out with computer simulations, employing the software COMSOL Multiphysics® to calculate the ... En savoir plus
A biotransformação de substratos utilizando enzimas imobilizadas em nanopartículas presentes num meio fluido (substrato), contido num bioreator CSTR, foi investigada. O software COMSOL Multiphysics foi usado para simular o sistema através do uso das equações de difusão de espécies ... En savoir plus
