马格努斯效应

在每一届国际足联世界杯 (FIFA World Cup™) 上,我们都能够看到激动人心的弧线球,Magnus 效应能够解释其中的原理。 此模型分析层流和湍流流态下瞬态和稳态流动的 Magnus 效应,还讨论了仿真结果,并将结果与文献中有关足球的实验测量相关联。 FIFA World Cup 是国际足联的商标。COMSOL AB 及其子公司和产品不与国际足联相关联,亦不由其担保、赞助或支持。

Modeling Deforming Meshes

This presentation and series of models show how to use the Deformed Mesh interfaces to model small and large translations and rotations of objects.

Modeling of Material Heating via the Beer-Lambert Law

This example exemplifies how to model the Beer-Lambert law using the core functionality of COMSOL Multiphysics. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "[Modeling Laser-Material Interactions with the Beer-Lambert Law](https://www.comsol.com/blogs/modeling-laser-material-interactions-with-the-beer-lambert-law/)".

Thermal Impact of a Borehole Heat Exchanger Array

This model shows how to compute an array of borehole heat exchangers (BHEs) for shallow geothermal energy production. The BHEs are simplified as ...

Sedan Interior Acoustics

这是轿车(也就是典型的硬顶家庭轿车)内的声学模型,模型在扬声器位置设置声源,还设置了阻抗条件,来模拟座椅、地毯和车顶衬里的软吸音表面。 模型仿真结果为车内压力、声压级和声强图,这几个绘图是将封闭空间内的声场进行可视化,并识别有问题的共振和驻波模式的重要工具,模型还确定了车内给定点处的频率响应。

Busbar, AC Analysis

这是使用交流分析的母线板构型。这一构型与《COMSOL Multiphysics 简介》一书中的入门教程类似,不过,这里添加了两个导体来表示母线板周围更真实的磁场情况,结果包括洛伦兹力、感应电流,磁通量和温度。

Shape Optimization of a Capacitor Design

This example exemplifies how to optimize the design of a capacitor through optimization. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "[Changing the Dimensions of a Model Using Shape Optimization](https://www.comsol.com/blogs/changing-the-dimensions-of-a-model-using-shape-optimization/)".

Design Sensitivities in a COMSOL Model

This example exemplifies how to compute the design sensitivities of your COMSOL Multiphysics® model. A more detailed description of the modeling process can be seen in the blog post "[Computing Design Sensitivities in COMSOL Multiphysics](https://www.comsol.com/blogs/computing-design-sensitivities-in-comsol-multiphysics/)".

Using COMSOL Models Together with Curve Fitting

This example exemplifies how curve fitting can be performed in COMSOL Multiphysics®, and how this can be applied to your modeling. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "[Curve Fitting of Experimental Data with COMSOL Multiphysics](https://www.comsol.com/blogs/curve-fitting-of-experimental-data-with-comsol-multiphysics/)".

Axial Homopolar Induction Bearing in 3D

此模型说明了轴向同极感应轴承的工作原理。在永磁体产生的磁场中,导电转子旋转产生感应涡流,涡流又产生与磁体的磁场方向相反的磁场,并感应产生与转子运动方向相反的力。转子的轴向位移总是与磁斥力达到平衡,因此,转子在中心处旋转时始终保持均匀间隙。模型计算了磁力随轴向位移变化的情况。 以下博客文章更详细地介绍和解释了这个模型:[使用 COMSOL Multiphysics® 模拟磁悬浮轴承](https://cn.comsol.com/blogs/modeling-magnetic-bearings-in-comsol-multiphysics/)。
