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

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

In this tutorial, the heat and mass transport equations are coupled to laminar flow in order to model exothermic reactions in a parallel plate reactor. It exemplifies how you can use COMSOL Multiphysics to systematically set up and solve increasingly sophisticated models using predefined ... 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

This is a model of a MEMS microphone solved in the frequency domain including the DC prestress effects. The model is set up using the Electromechanics multiphysics interface, Thermoviscous Acoustics, and Pressure Acoustics. The microphone consists of a perforated plate and a prestressed ... 詳細を見る

In this example, the structural integrity of a cylinder made by a fiber composite is assessed both at the macroscale and at the microscale level. Along with macroscale analyses, structural composites need microscale stress and failure analyses to identify the critical constituents in ... 詳細を見る

Intended as a tool for early proof of concept in capacitive touchscreen device development, the Touchscreen Simulator app evaluates a simulated capacitance matrix as well as the electric field norm. The app computes the capacitance matrix of a touchscreen in the presence of a human ... 詳細を見る

This tutorial model explains how to extract lumped matrices by means of the Stationary Source Sweep study. The capacitance matrix of a five-terminal system is used to infer the position of a metallic object similar to real-world capacitive position sensors. The example illustrates the ... 詳細を見る

This example demonstrates a simulation setup for exciting surface plasmon polaritons using Otto and Kretschmann configurations. The underlying mechanism is enabled by the interplay between total internal reflection and evanescent-wave coupling phenomena. It also calculates the ... 詳細を見る

During manufacturing or in-service use, the geometric shape of structural components can deviate from their intended design. For example, a hole may lose its perfectly circular form, making it important to measure and control this deviation. The process of quantifying such deviations is ... 詳細を見る
