In every system where there is conduction of electric current, and where the conductivity of the material is finite, there will be electric heating. Electric heating, also referred to as Joule heating, is in many cases an undesired by-product of current conduction. This model simulates 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

This example focuses on the species transport within the gas diffusion layers (GDLs) of a proton exchange membrane (PEM) fuel cell. The geometry models a cell with two adjacent flow channels of different pressures, a situation that may occur in a cell with serpentine flow channels, or in ... 詳細を見る

ヒートパイプは, 作動流体の気化, 物質移動, 凝縮を通じて熱を効率的に伝達するように設計されています. ヒートパイプは, 電子機器の冷却など, 熱制御が重要となるさまざまな用途で使用されています. ヒートパイプ内部では, 高温側と低温側の温度差と蒸気圧の温度依存性により, 蒸気室全体に圧力差が生じます. この圧力差により, 蒸気は高温側から低温側へと移動します. 高温側では, 蒸発が蒸気-ウィック界面でヒートシンクとして機能し, 逆に低温側では凝縮が熱源として機能します. このモデルは, ... 詳細を見る

In this example water ponded in a ring on the ground moves into a relatively dry soil column and carries a chemical with it. As it moves through the variably saturated soil column, the chemical attaches to solid particles, slowing the solute transport relative to the water. Additionally ... 詳細を見る

This tutorial model solves for an inductively coupled plasma reactor with RF bias (also known as ICP/CCP reactors) in a mixture of argon/chlorine. The model computes the fluid flow and gas heating. Important aspects and strategies for modeling electronegative discharges are discussed. 詳細を見る

Rotating cylinder Hull cells are an important experimental tool in electroplating and electrodeposition and are used for the measurement of nonuniform current distribution, mass transport, and throwing power of plating baths. The model reproduces the results for a commercially available ... 詳細を見る

Example of membrane dialysis with a two-layered membrane. A second Reaction Engineering component models a tank connected to the inlet and outlets of the dialysate channel. 詳細を見る

This model compares the solution to the model equations of a tubular reactor using Danckwerts inlet and outlet conditions. A second almost identical model is defined with extra inlet and outlet sections where no reactions occur. The concentration at the beginning of the inlet section is ... 詳細を見る

Modeling curing is important in a wide variety of applications such as for devices utilizing polymer materials, rubber materials, plastics, and concrete. Curing is usually an exothermic reaction. In the current example, curing of butyl rubber is studied in a 3D mold for an automotive ... 詳細を見る
