This model shows how to analyze a tuning fork based piezoelectric rate gyroscope. The reverse piezoelectric effect is used to drive an in-plane tuning fork mode. This mode is coupled to an out of plane mode by the Coriolis force and the resulting out of plane motion is sensed by the ... 詳細を見る

This model shows how to analyze a simple, cantilever based, piezoelectric energy harvester. A sinusoidal acceleration is applied to the energy harvester and the output power is evaluated as a function of frequency, load impedance and acceleration magnitude. 詳細を見る

This tutorial shows how you can use the Electromechanics interface in COMSOL's MEMS Module to model Electrostriction. Electrostrictive materials (e.g. PMN-PT) exhibit nonlinear strain as a function of electric field. This 2D axisymmetry model uses a parametric sweep of voltage to ... 詳細を見る

Electroless deposition or plating is a non-galvanic plating method that does not require any external electrical power. This technique is typically used for electroless plating of nickel, silver, gold and copper. In electroless deposition, partial oxidation and reduction reactions ... 詳細を見る

High-performance liquid chromatography (HPLC) is a common method of separating, identifying, and quantifying each chemical compound in a mixture. HPLC is found in the pharmaceutical, biotech, and food industries. The Liquid Chromatography app simulates the separation of two species ... 詳細を見る

This tutorial simulates a small vibrating hemispherical particle in water. The particle has a radius of 1 mm and is oscillating in the axial direction at a frequency of 50 kHz. The vibrations induce acoustic waves in the fluid. The example demonstrates how to set up a thermoviscous ... 詳細を見る

This model presents the static field modeling of an outward flux focusing magnetic rotor using permanent magnets. This magnetic rotor is also often called a Halbach rotor. The use of permanent magnets in rotatory devices such as motors, generators and magnetic gears is increasing. The ... 詳細を見る

The incompressible boundary layer on a flat plate in the absence of a pressure gradient is usually referred to as the Blasius boundary layer. The steady, laminar boundary layer developing downstream of the leading edge eventually becomes unstable to Tollmien-Schlichting waves and finally ... 詳細を見る

このモデルは, COMSOL Multiphysics を使用して, 異なる次元で定義された現象を完全に連成した方法でモデル化する方法を示しています. ほとんどの場合, 反応速度式は反応物と生成物の濃度の関数として定義されますが, 吸着反応では活性部位または表面複合体の表面濃度もモデル化する必要があります. これは, リアクターのバルク内の質量バランスを, デバイスの表面のみに存在する種の質量バランスと結合する必要があることを意味します. このデバイスは, 触媒, バイオチップ, 半導体部品, または表面固有の化学種を含む任意のプロセスである可能性があります. ... 詳細を見る

This tutorial demonstrates how to compute the periodic steady-state solution of a nonlinear model problem using an optimization solver. The solver modifies the initial conditions at the beginning of a period to match the solution at the end of the period. The model solves much faster ... 詳細を見る
