Oscillating chemical reactions were long thought to simply not exist in homogeneous solution, and even the poster child, the Belousov–Zhabotinsky reaction, met such an initial skepticism, that even though it was discovered in 1951, it took almost 20 years for it to gain widespread fame. ... 詳細を見る

このモデルは, 高レート充電中の角柱型電池の内部温度分布を計算する方法の例を示します. 電気化学は, 熱伝達モデルと結合した集中二電極モデルによって記述されます. 熱伝達モデルには, 集電体および端子におけるジュール熱の影響に加え, ゼリーロールにおける電気化学的加熱 (過電圧による) の寄与も考慮されています. ゼリーロールは, 電池層の構造と寸法を考慮した異方性特性を用いて記述されます. 詳細を見る

An electrostatically actuated MEMS resonator is simulated in the time and frequency domains. The device is driven by an AC + DC bias voltage applied across a parallel plate capacitor. The dependence of the resonant frequency on DC bias is assessed, and frequency domain and transient ... 詳細を見る

Induced eddy currents and associated thermal loads is of interest in many high power AC applications. This example is of general nature and illustrates some of the involved physics as well as suitable modeling techniques in the AC/DC Module. In this model a metallic plate is placed ... 詳細を見る

The Poroelasticity interface couples Darcy's law and solid mechanics to assess deformation of porous media that results from fluid withdrawals. The model builds on top of the Terzaghi Compaction example. Results from Terzaghi compaction and Biot poroelasticity analyses are compared to ... 詳細を見る

This tutorial analyzes the resistive heating (Joule heating) of a busbar assembly designed to conduct a direct current from a current source to the anode in an electrolysis process. 詳細を見る

The Schmidt-Cassegrain Telescope demonstrated in this tutorial is a classic design using an aspheric corrector lens and two spherical mirrors. The aspheric corrector is created using the 'Aspheric Even Lens 3D' part from the Ray Optics part library. 詳細を見る

Model of the sound radiation from a circular duct with uniform flow. The convected acoustic problem is described using the linearized potential flow equations, solved in the frequency domain. The acoustic inlet is treated including higher order modes using the Port boundary condition and ... 詳細を見る

This tutorial models an ICP reactor by solving plasma fluid type equations fully coupled with the homogeneous and time-independent electron Boltzmann equation in the classical two-term approximation. The approximated Boltzmann equation is solved for each position of space and is coupled ... 詳細を見る

Streamers are transient filamentary electric discharges that can develop in a nonconducting background in the presence of an intense electric field. These discharges can attain high electron number density and consequently a high concentration of chemical active species that are relevant ... 詳細を見る
