This tutorial model solves for an inductively coupled plasma reactor in a mixture of argon/oxygen. The model computes the fluid flow and gas heating. Important aspects and strategies for modeling electronegative discharges are discussed. 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

This model analyzes a piezoelectric microelectromechanical system (MEMS) speaker. The speaker, composed of four triangular membranes, uses a layer of lead zirconate titanate (PZT) material with two electrodes on top of a silicon layer as actuators. The triangular membranes are separated ... 詳細を見る

Aldicarb is a commercial pesticide, used on a variety of crops, including cotton, fruits, potatoes, and beans. This arises in the possibility that the general population may be exposed to aldicarb through the ingestion of contaminated water and foods. This example looks at the ... 詳細を見る

This tutorial presents a study of positive and negative corona discharges in dry air at atmospheric pressure. The discharges are sustained within two electrodes in a coaxial configuration by a high voltage DC source applied to the inner electrode. Two different types of models are used: ... 詳細を見る

このチュートリアルでは, サーペンタイン型の流路パターンを用いた低温 PEMFC における電流分布について考察します. セルは対向流モードで動作し, 酸素と水素の入口流路は反対側に配置されます. セルが良好な性能を得るために自己加湿を利用するよう, 比較的乾燥した入口ガス組成が使用されています. 詳細を見る

This model shows how to include the nonlinear (large signal) behavior of certain lumped components in a simplified loudspeaker analysis. The mechanical and electrical system is modeled using an equivalent electrical circuit. The large signal compliance CMS(x) and force factor BL(x) are ... 詳細を見る

This model illustrates how to perform prestressed eigenfrequency and frequency response analyses in a contact problem. A circular plate is squeezed between two thicker plates. The peak of the prestressed frequency response analysis is compared with the prestressed eigenfrequencies as ... 詳細を見る

This example shows how the mixing capability of a stirred vessel can be evaluated. To efficiently reach the steady operational conditions the turbulent flow is solved for using a frozen rotor analysis, and a following time dependent simulation. When a quasi-steady flow field has ... 詳細を見る

The present model example is based on Copper Deposition in a Trench model available in Electrodeposition Application Library. The nonuniform deposition along the trench surface leads to formation of a cavity/void. Since the Deformed Geometry interface cannot handle topological changes, ... 詳細を見る
