流体ダンパーは, 軍事機器における衝撃吸収, 土木構造物における地震や風による振動の抑制など, 様々な用途に使用されています. 流体ダンパーは, 機械エネルギーを熱に変換することで機能します. このモデルは, 流体ダンパーにおける粘性加熱とそれに伴う温度上昇の現象を示します. 粘性加熱はマイクロ流体デバイスにおいても重要です. マイクロ流体デバイスでは, 断面積が小さく長さが長いため, 大きな発熱が発生し, 結果として流体の流れに影響を与える可能性があります. このモデルでは, 共役熱伝達, 層流, 移動メッシュの各インターフェースを用いて時間依存スタディを実施します. 詳細を見る

This simple model demonstrates how to use the Semiconductor Optoelectronics interfaces to model a simple GaAs PIN diode structure. Both the stimulated and spontaneous emission in the semiconductor are accounted for. The corresponding absorption of the light and the associated change in ... 詳細を見る

The heat exchanger in this tutorial model contains a dynamic wall with an oscillating wave shape. The deformation induces mixing in the fluid and reduces the formation of thermal boundary layers. Hence, it increases heat transfer between the walls and the fluid. In addition, the wave ... 詳細を見る

Permanent magnet (PM) motors are used in many high-end applications, such as in electric and hybrid vehicles. An important design limitation is that the magnets are sensitive to high temperatures, which can occur through heat losses caused by currents, particularly eddy currents. In ... 詳細を見る

This model shows how shape optimization can be used design the coils of an ICP reactor to obtain plasma uniformity. The reactor in study is a planar ICP with the coils distributed along the radial direction. The Optimization study step is used to find the best coil placement so that the ... 詳細を見る

Squeezed-film gas damping is a critical aspect of many MEMS transducers and actuators. In accelerometers, for example, inertia produces a motion that the device detects. A typical structure connects a large proof mass to surrounding structures with elastic beams, which forms a mechanical ... 詳細を見る

Inductive devices experience capacitative coupling between conductors at high frequencies. Modeling this phenomenon requires that you describe electric fields that have components both parallel with and perpendicular to the wire. This consideration might lead to the conclusion that a 3D ... 詳細を見る

This suite of examples illustrate the modeling of selective NO reduction, that occurs as flue gases pass through the channels of a monolithic reactor in the exhaust system of a motored vehicle. The simulations are aimed at finding the optimal dosing of NH3, the reactant that serves as ... 詳細を見る

This tutorial shows how to solve the full time-dependent wave equation in dispersive media such as plasmas and semiconductors. The 2D TM in-plane wave model solves for the vector potential from the wave equation and for an auxiliary electric polarization density from an ordinary ... 詳細を見る

This example demonstrates how to optimize the thickness of a microelectromechanical systems (MEMS) mirror coating material for maximum reflectivity. To reduce the simulation time, a Layered Impedance Boundary Condition is used to model the thin coating material on top of the metallic ... 詳細を見る
