In this model, we introduce a cloaking method using an electrically tuned monolayer of graphene. We will show that when a cylindrical dielectric scatterer is covered in graphene, the scattering cross section is greatly reduced at the designated frequency, making it electromagnetically ... 詳細を見る

This tutorial studies the propagation of high intensity focused ultrasound (HIFU) though a tissue phantom. HIFU is used in many different biomedical applications such as thermal ablation of tumors, transcranial HIFU surgery, shock wave lithotripsy, etc. A HIFU transducer typically ... 詳細を見る

This is a tutorial model that illustrates the use of the scattered field formulation in acoustics. A solid object (here an ellipsoid) is hit by an incident plane wave field (background pressure field). The model solves for the scattered field. The model uses a PML and a far-field ... 詳細を見る

次のモデルは, 流れてくる流体に対して直角に流路内に置かれた長い円筒を過ぎる非定常で非圧縮性の流れを調べます. 円筒は流れの中心からいくらかオフセットされており, 定常状態の対称的な流れを不安定にします. 周期的な流れのパターンが現れるのに必要なシミュレーション時間は予測が困難です. 重要な予測因子は, 円筒の直径に基づくレイノルズ数です. 値が 100 未満の低い場合, 流れは定常です. このシミュレーションでは, レイノルズ数は 100 に等しく, 発達したカルマン渦列が生じますが, 流れはまだ完全に乱流ではありません. 詳細を見る

This example shows how to perform a fatigue analysis of a structure subjected to random vibrations. Times to failure using the cycle counting models according to Bendat and Dirlik are compared. 詳細を見る

A thermoacoustic engine is a device with no moving parts that can generate acoustic energy from temperature gradients within the engine. It uses the relationship between the movement of oscillating air and the temperature changes in the air compressed and expanded by the acoustic waves. ... 詳細を見る

This example solves the problem of finding the optimal thickness profile of a flywheel, so that the moment of inertia is maximized without increasing the mass or the maximum stress in the flywheel. 詳細を見る

Induction pumps are used in high temperature cooling systems. The principle of operation is equivalent to a linear three phase induction motor. The lack of moving parts and the pumped liquid being kept in a hermetically closed system are clear advantages. This model shows how to simulate ... 詳細を見る

Developments in the last decade have made circuit quantum electrodynamics (cQED) the leading architecture for quantum computation. cQED is the solid-state version of cavity QED, which studies the basic light-matter interactions at the quantum level. This model examines one of the main ... 詳細を見る

The installation verification application can be used to help verify that your COMSOL Multiphysics® or COMSOL Server™ installation works as expected on your hardware platforms and operating systems. The app automatically loads and runs a suite of test models and compares the results with ... 詳細を見る
