The future development of electric vehicles is now strictly linked with their batteries. In parallel of the actual research focused on the development of new materials and increase their performances in terms of energy, power, cost, durability and weight, it is necessary to develop modeling tools. The simulations are helpful for improving the knowledge of both physical and chemical phenomena, ...

Among the new features introduced by the latest versions of COMSOL Multiphysics® software, the opportunity of building up customized model interfaces by exploiting the Application Builder is for sure one of the most promising. Arising from this concept, the Certified Consultant BE CAE & Test presents a COMSOL app to analyze the thermal behavior of an electronic Surface-Mount Device (SMD). The ...

During Physical Vapor Transport (PVT) growth of single 4H-SiC crystal and subsequent cooling down, thermal stresses lead to the multiplication of dislocations that are non-desirable for the semiconductor applications of this material. These dislocations induced by thermal stresses could be reduced by an appropriate control of the thermal gradients inside du crystal during its growth and cooling ...

Introduction: RFID system uses a Transponder and the near field communication (NFC) antenna and a matching circuit (Figure-1) in which at least latter two must be optimally designed for a higher efficiency. Typically, RFID antennas are flat inductive coils with 2 to 4 turns and are printed directly on the PCB. The larger antenna size implies larger operating distance whereas, the number of ...

Introduction Droplet-based microfluidics is a large source of research for scientists of new biotechnologies, aerosols or other 2D-Microfluidics devices. Here, we will focus on an industrial application of a 3D microfluidic device : the PH2DG, Pneumo-HydroDynamic Droplet Generator. The aim of the process is to produce mono-disperse, regular pattern of droplets, with a minimum size. To use it in ...

In order to predict the residual mechanical state of assemblies during pulsed laser welding, mechanical and metallurgical behaviors of materials need to be precisely characterized. Based on experimental data and analyses , a numerical model is developed in COMSOL Multiphysics® software to take into account the predominant effects identified for TA6V. First of all, the metallurgic behavior ...

Introduction: The drawbacks of most commercial “advanced battery” solutions are high price, danger, and low recyclability. The most cost efficient, environmental-friendly, and safest solutions so far is based on lead-acid electrochemistry, a proven technology for more than 150 years. Key problems of this technology are however the limited cyclability which results in a reduced lifetime and high ...

Relative permeability maps for steady-state two-phase flow in porous media, delivered by implementing the DeProF model  algorithm, were integrated within COMSOL Multiphysics® software  to resolve field-scale flows in porous media. The mechanistic model DeProF , predicts the relative permeability of oil and water in terms of the capillary number, Ca, the oil/water flowrate ratio, r, ...

In general, macroscopic two-phase flow in porous media is a mixture of connected and disconnected oil flow. The latter is expressed as ganglion dynamics and drop traffic flow, patterns observed experimentally in pore network models [1,2] and real porous media [3,4]. This characteristic was adversely not taken into account in previous modeling approaches. The mechanistic model DeProF , ...

Lithium-sulphur (Li-S) batteries have the potential to surpass the energy storage capability of Li-ion batteries due to their high theoretical gravimetric energy density of 2700 Wh/kg. However, the processes which drive the system behaviour are much more complex than those in a Li-ion cell, meaning that controlling them to realise energy densities much above 350 Wh/kg is challenging. In a Li ...
