A thermal model to predict the heat generation during the charge and discharge of a battery pack is an essential tool to manage the thermal behavior, performance and life of the batteries. In this work, a battery cell is modeled in COMSOL Multiphysics® using the Batteries and Fuel Cells ... Mehr lesen
A multilayer polymer coating is applied to carbon steel pipelines installed in the sea to protect against corrosion and to insulate to maintain the temperature. For field joint coatings, both thermosets (like polyurethane) and semi-crystalline thermoplastics (like polypropylene) are ... Mehr lesen
Respect to the previous approaches, in this communication the electrochemical and chemical kinetics as well as the transport phenomena, were modelled at very high level of theory, taking into account all the parameters affecting the galvanic process, including turbulent convection ... Mehr lesen
The main purpose of a drive unit is to transform the electrical signal at its terminals into acoustic waves via two transduction mechanisms: electro-mechanical and mechano-acoustical. In this paper only the electro-mechanical transformation is discussed in view of a future optimization ... Mehr lesen
Integration or retrofitting of photocatalytic air purifying units into HVAC (Heating, Ventilation and Air Conditioning) equipment is an interesting approach for abating indoor air pollution and removal of volatile organic compounds. An attractive possibility is the use of glass fiber ... Mehr lesen
A two-dimensional steady model of the natural convection around a cylinder is solved numerically using COMSOL Multiphysics software. The cylinder receives non-uniform heat from a radiating panel, which is assumed to be sufficiently far away so that the flow around the panel does not ... Mehr lesen
Our goal is to reproduce the key features of carangiform swimming by running 2D simulations which fully exploit the Fluid-Structure Interaction interface of COMSOL Multiphysics software. Fish swimming is an important area of research, with relevant developments on biomechanics, robotics ... Mehr lesen
We investigate a prototype concept of a back-up electricity device where we use liquid formic acid (FA) to produce a mixture of carbon dioxide (CO2) and hydrogen (H2) which is used in a PEM fuel cell, Fig. 1. In the fluidized bed reactor the liquid FA is decomposed to a gaseous mixture ... Mehr lesen
GalFeNol is a new Giant Magnetostrictive Material that can be used in energy harvesting especially in vibration reduction applications, thanks to the Joule and Villari effects. A 3D-model of GalFeNol rod is stressed by a time varying longitudinal force of 1000 N. The study has been ... Mehr lesen
A micro steam methane reformer is a complex product consisting of multiple units. For the virtual functional product development it is necessary to validate these sub models separately. Therefore a reactor was designed to analyse kinetics of chemical reactions. The reactor design is ... Mehr lesen
