This example models the temperature profile in a liquid-cooled prismatic battery pack during a high-rate charge. The pack consists of 16 prismatic battery cells connected by busbars, placed on an aluminum plate containing four cooling channels. The battery pack is assumed to have two ... 詳細を見る

In a redox flow battery electrochemical energy is stored as redox couples in the electrolyte, which is stored in tanks outside the electrochemical cell. During operation, electrolyte is pumped through the cell and, due to the electrochemical reactions, the individual concentrations of ... 詳細を見る

Plate reactors running under continuous conditions have emerged as candidates to replace batch reactors, primarily in fine chemicals and pharmaceuticals production. One of the advantages of the plate reactor design is that it allows for efficient temperature control of the reacting ... 詳細を見る

This example shows how to use the Parameter Estimation and Experiment features in the Reaction Engineering interface for optimization with multiple experimental data input files. The application finds the Arrhenius parameters of a first order reaction where Benzene diazonium chloride ... 詳細を見る

In a polymerization reactor for polyester manufacturing, the mixing in the reactor is achieved by impinging turbulent jets of reactants onto each other. The turbulence affects the reaction kinetics and quality of the polymer linkage. Turbulent flows involving rapid reaction kinetics are ... 詳細を見る

In this tutorial, the heat and mass transport equations are coupled to laminar flow in order to model exothermic reactions in a parallel plate reactor. It exemplifies how you can use COMSOL Multiphysics to systematically set up and solve increasingly sophisticated models using predefined ... 詳細を見る

This example replicates the results of the Jelly Roll tutorial example using a flattened representation of the wound spiral-based geometry. See that model entry for details on the background, original geometry, materials, and the general physics setup. Mapping the original problem to a ... 詳細を見る

リチウムイオン電池の負極グラファイト電極上の銅コレクターは, 過放電時に溶解することが確認されています. 溶解により集電体が不可逆的に損傷し, 溶解した銅イオンが再析出してデンドライトを形成する可能性があるため, 安全上の懸念事項となります. 電池は通常, 過放電を回避するために, セルレベルまたはパックレベルのいずれかで指定された電圧制限内で動作します. しかし, パック内では個々のセル間の電荷不均衡により, あるいはこのチュートリアルで部分的に調査するように, 単一の電池セル内の電極の局所的な不均一性により, 過放電が発生する可能性があります. ... 詳細を見る

Corrosion induced due to alternating current (AC) is evident in the oil and gas industry, particularly when a pipeline is in close proximity to the high power transmission lines. A numerical model presented here first evaluates the effect of direct current (DC) applied potential on ... 詳細を見る

This is a demonstration of how to use the thermodynamics functionality in the COMSOL Multiphysics® software to make flash calculations. A flash calculation is an equilibrium calculation of a system where several species and phases are present at the same time. The system in ... 詳細を見る
