The thermal behavior of lithium ion batteries could be investigated by efficient simulation method [1,2]. Here, we developed an electrochemical-lumped thermal analytical model to analyze the thermal response and heat breakdown of a pouch LiNi1/3Co1/3Mn1/3O2 battery (3Ah) under fast-discharging conditions at 7C(environment temperature:20℃). The key parameters of the proposed model (such as ...

This paper addresses one of the major challenges in water-flooded oil reservoirs, which is early water breakthrough due to the presence of high permeable layers in the media. COMSOL Multiphysics is used to model two phase (water and oil) flow in dual-permeability porous medium at micro-scales. The heat transfer module is coupled with the laminar two-phase flow interface, because temperature ...

An experimental program has been developed, with the purpose of evaluating the reliability in building diagnosis and characterization of an integrated analysis of several parameters related to heat transfer process through the building material. The Infrared Thermography Technique (IRT) has been applied. Experimental measurements have been carried out on a concrete structure with an inside ...

Chocolate is a pleasurable product largely consumed over the world. It is known that ingredients, process and particle size distribution largely impact the chocolate sensory perceptions. It was hypothesized that a suitable choice of chocolate size and geometry modifies in-mouth melting and aroma release and modulates flavour and oral texture perception. Since in-vivo experiments on chocolate ...

The subsurface thermal structure in presence of groundwater recharge/discharge has been obtained by applying the Robin type boundary condition at the earth’s surface. The Robin type boundary condition involves the effect air temperatures at the surface which are taken as exponentially varying with time and the initial condition which is taken as exponential function of depth. The numerical ...

The formation of porosities in spot laser welding depends on complex thermo-hydraulic phenomena. To understand and control these mechanisms, the COMSOL Multiphysics® software is used to model both the interaction and cooling stages of an isolated impact made with a Nd:YAG pulsed laser. The model is based on the Phase Field method in order to apprehend the evolution of the liquid-gas interface ...

Thermocouples have been used for measurement of temperature ever since the discovery of Seebeck effect. Though the voltage output of a thermocouple is a function of the temperature difference between hot and cold junctions, the response time and the magnitude of voltage depends on the geometry and material of the thermocouple also. This report deals with the study of the mineral-insulted ...

Self-heating is a problem to consider for Ultrasound Imaging probes. Since the probe is in contact with the skin, it’s necessary to find a solution to lower the front face temperature in order to avoid patient discomfort, even at the most demanding operating condition. One solution consists in the design of a device that drains the heat from the front to the rear of the transducer, where a ...

INTRODUCTION The purpose of this work is to verify the effect of Multigrid method on the CPU time for the resolution of the heat transfer model, based on the Finite Element Method (FEM), in order to simulate the laser surface remelting (LSR) of the Al–1.5 wt.% Fe alloy. To accelerate the convergence of Single grid methods, Multigrid method (MG) was employed in order to reduce the CPU time. In ...
