Multi-Scale and Multi-Dimensional (MSMD) modeling approaches have been proposed to simulate the thermal, electrical distributions and concentration behaviors of large size pouch cell. This approach is based on coupling of the energy balance with the Newman’s electrode model. Newman’s 1D electrochemical model is often used for small size batteries but not sufficient enough for large size where ...

The application of pulsed electric fields (PEF) is well known in the food industry as an advanced technology for mass transfer improvement. A new potential adaptation area of PEF could be extracting a valuable antioxidant called polyphenol from wet olive pomace (WOP) which is a by-product of olive oil production. The modelling includes the PEF effects on the WOP which is flowing through a ...

The microwave heating and processing of heterogeneous material is usually simulated using a set of coupled PDE equations in an homogeneous medium. Nowadays it is possible to describe more accurately the process with a suitable description of the heterogeneities that is at the grain level. Many authors work with spheres (circles) to represent the grains but it is difficult to achieve an ...

Photothermal therapy through Gold Nanorods (GNRs) is a new approach for the minimally invasive treatment of cancerous tissue. In order to design the proper settings, it is important to study the thermal effect that are induced close to the nanoparticle (nanoscale model), in the close vicinity and in the cancerous tissue (microscale model). A temperature dependent 2D-model of this particular ...

A model for the conjugate simulation of heat and moisture transfer inside porous materials and fluid domains is implemented in COMSOL Multiphysics®. The results of this model are compared with those obtained through a simplified approach: the line-source approach. The models are both validated with experimental data and with numerical results from other authors. On the one hand the conjugate ...

The paper studies the thermal modeling and simulation of photovoltaic cells suitable for use in highly concentrated solar flux (> 1000 suns). The cells studied are those of GaAs kind. These cells are a very good alternative to be studied instead of more complex multi junctions cells. The objective is to find a simple and inexpensive way to remove heat from PV modules and to keep the electrical ...

The dynamical fluorescent micro-thermal imaging (FMI) experiment has been used to investigate the phonon-magnon interaction in the 1D Heisenberg antiferromagnet La5Ca9Cu24O41. This material shows highly anisotropic heat conductivity due to the efficient magnetic heat transport along the spin ladders in the compound carried by magnetic excitations (magnons). To extract information on the phonon ...

In all implantable medical devices, one main challenge is to assure no water penetrates in the electronic part of the system. To be able to transmit the electronic information from the inside of the device to the lead without any water infiltration, we used a complex part called feed through. This piece is made of four different materials: titanium, alumina, gold and platinum. It is ...
In this paper a two dimensional time dependent model is developed and assessed to describe the interrelated processes of conduction, convective heating and ablation of non pyrolytic ablative material. An aerothermochemical analysis for the process of non-pyrolitic composite material regression in advanced solid-propellant rocket motors has been conducted. The analytical approach is similar ...

Steam Generator Test Facility (SGTF) is set up in IGCAR to optimize the design of Steam Generators (SG) for Fast Breeder Reactors. In the SG of SGTF heat exchange takes place from sodium which enters at 525 ºC and leaves at 355 ºC temperature to the water/steam which enters at 235 ºC and leaves at 493 ºC. To reduce the steady state differential temperature and thermal shock during transients, ...
