This model approximates 3D spherical transport using a 1D model. Many models of industrial-transport problems allow the assumption that the problem is spherically symmetric. This assumption is of great importance because it eliminates two space coordinates to result in a 1D problem that ... 詳細を見る

A square airbag is inflated using constant air pressure. In some regions of the airbag the material wrinkles during inflation, as negative principal stresses develop. The wrinkling membrane model within the tension field theory gives a correct description of the stress distribution and ... 詳細を見る

Journal bearings are used to carry radial loads, for example, to support a rotating shaft. A simple journal bearing consists of two rigid cylinders. The outer cylinder (bearing) wraps the inner rotating journal (shaft). The new thin-film flow user interfaces of the CFD Module enables ... 詳細を見る

The underlying physics of a capacitively coupled plasma is rather complicated, even for rather simple geometric configurations and plasma chemistries. This model benchmarks the Capacitively Coupled Plasma physics interface against many different codes. 詳細を見る

RFIDs are used in a multitude of applications such as tracking or identifying consumer products and their packaging. An RFID system consists of two main parts: A tag or transponder with a printed circuit-board (PCB) antenna A reader unit with a larger RF antennaThe reader antenna ... 詳細を見る

Chemical vapor deposition (CVD) is an important step in the process of manufacturing microchips. One common application is the deposition of silicon on wafers in low pressure reactors to obtain uniform deposition thicknesses. This example models the coupled reaction kinetics, fluid ... 詳細を見る

This model solves the Boltzmann equation in the two-term approximation for a background of molecular and atomic hydrogen. Electron mobility and source terms are computed by suitable integration of the electron energy distribution function over electron impact cross sections. 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

The External Material functionality makes it possible to program your own material models for cases when the built-in material models are not sufficient. For structural mechanics, you have the possibility to either completely define the material model in a domain, or to add an inelastic ... 詳細を見る

This model presents the flow noise generated by flow past the so-called tandem cylinder configuration. The test is part of the “First Workshop on Benchmark problems for Airframe Noise Computations”. The tutorial model shows the steps involved in a flow-induced noise simulation in COMSOL ... 詳細を見る
