In signal integrity (SI) applications, time-domain reflectometry (TDR) is a useful technique for analyzing the discontinuity in a signal path by observing the reflected signal strength. The reflected signal distorts the input pulse mainly by impedance mismatch if there is no external ... 詳細を見る

Surface chemistry is often an overlooked aspect of reacting flow modeling. This tutorial model shows how surface reactions and species can be added to study processes like chemical vapor deposition (CVD). The tutorial then models silicon growth on a wafer. Initially, the example uses a ... 詳細を見る

Powder compaction is a key process in powder metallurgy, where it gives the flexibility to produce quality products of complex shapes for sintering. The density of the compact is a key factor to determine the overall quality of the sintered product, as regions with lower density could ... 詳細を見る

This tutorial model uses a heat sink geometry from the Part Library. The tutorial shows different approaches to heat transfer modeling when studying the cooling of an electronic chip. In the first part, only the solid parts are modeled, while the convective airflow is modeled using ... 詳細を見る

シェル ‐ チューブ熱交換器は, 石油精製所やその他の大規模な化学プロセスでよく使用されます. このモデルでは, 異なる温度の2つの分離された流体が熱交換器を流れ, 1つはチューブ (チューブ側) を, もう1つはチューブの周りのシェル (シェル側) を流れます. シェル ‐ チューブ熱交換器の最適なパフォーマンスは, いくつかの設計パラメーターと動作条件によって左右されます. このモデルは, 熱交換器モデルを設定するための基本原則を示しています. これは, パラメータースタディや, 腐食, 熱応力, 振動などの追加効果を伴う, ... 詳細を見る

This tutorial models how the relative humidity of the inlet gases impacts the performance of a low-temperature polymer electrolyte membrane-electrode assembly. The model includes humidity-dependent ionomer (electrolyte) conductivities, gas phase mass transport and water ionomer ... 詳細を見る

Copper electrowinning is the process of copper extraction from an electrolyte solution and its deposition at the cathode surface, by passing an external current through the electrolytic cell and using an insoluble anode. During the process, oxygen bubbles are generated at the anode ... 詳細を見る

Lead-acid batteries are widely used as starting batteries for various traction applications such as cars and trucks and so forth. The reason for this is the fairly low cost in combination with the performance robustness for a broad range of operating conditions. However, one drawback of ... 詳細を見る

The noise emitted from an electrical machine can have many sources. In this example, acoustic noise from vibrations created by magnetic force variation is studied. Such noise is often audible at twice the excitation frequency but can also occur at higher frequencies or harmonics of the ... 詳細を見る
