Polymer–metal is a kind of new composite materials rather than traditional metal packaging materials. It has both features of polymer film and sheet metal. However, the polymer film will damage in the sheet metal forming process. Therefore, we try to established a sheet metal forming model with punch and die in the study, based on solid mechanics module of COMSOL Multiphysics® software. We ...
分别从软件模拟和晶体生长实验两方面对衬底表面的温度分布进行研究，进而达到控制 AlN 蒸气在衬底表面过饱和度的目的。理论上，结合异质形核理论（图1 (a)-(c)），采用 COMSOL Multiphysics® 模拟软件对坩埚结构的温度分布进行模拟仿真(图1(d))，模拟结果表明：复合型衬底可以显著地改变衬底表面的温度分布，进而改变衬底表面 AlN 气氛的过饱和度，实现对晶体生长驱动力的控制；实验上，采用 PVT 法 AlN 晶体的生长实验验证了软件模拟结果。采用复合型衬底生长 AlN 晶体时，通过对衬底表面的温度分布调控，如图1 (c)-(g)所示，可有效地控制晶体生长驱动力，进而实现形核位置和形核数量的控制[2，3]，经过 6~10 h AlN 晶体生长后，可获得较大直径的 AlN 单晶。拉曼光谱和 XRD 双晶摇摆曲线测试结果表明，晶体具有很好的结晶性能。

Adequate cooling of beverages is a major issue in planning of several types of events, e.g. poster sessions at conferences. One crucial factor is the time needed to cool beverages from its initial temperature to the desired drinking temperature. We present a way to determine a close approximation for the cooling behavior of three types of commonly used beverage containers using COMSOL ...

随着电力工业的快速发展，母线板作为汇集、分配和传送电能的装置，广泛应用于各个电工领域。由于流过母线板的电流一般较大，其温升发热问题不容忽视。该问题涉及电磁场、温度场、流场及位移场等多个物理场的综合。为了更好地研究其发热散热问题，本文采用 COMSOL Multiphysics® 多物理场直接耦合分析软件，基于有限元理论，在考虑设备几何形状和材料物理特性影响的基础上，对母线板进行三维建模。分别在瞬态和稳态情况下对母线板进行电—热—力耦合场分析，电—热—流耦合场分析，从而研究母线板的温度、电流密度分布规律和由于热膨胀引起的形变大小。最后加入层流，分析在考虑气流冷却效应时，母线板的散热情况，并对仿真结果进行研究分析。

Although microwave heating has been studied in great detail, microwave combination heating has not. This work investigated this in a novel microwave combination system that heats the sample through a combination of microwaves and hot air. The study used a coupled electromagnetics-multiphase porous media model in COMSOL to determine the effect of combining different heating modes on heating ...

Distributed feedback lasers improve the performance of standard Fabry-Perot laser designs by including a wavelength-selective grating that provides superior output, spectral purity and temperature stability. Laterally-coupled distributed feedback (LC-DFB) lasers with the use of higher order gratings have a grating that has been patterned out of the waveguide ridge which allows for simplified ...
