带有防腐层的金属管道被广泛应用到油气输送,金属管道表面缺陷的存在会对管道运行产生安全隐患,如何检测防腐层下金属表面缺陷一直是无损检测领域的难题;本文设计了一种基于电容成像技术的新型电容成像探头(图1),利用该探头对不同深度的表面缺陷进行线扫描研究,并搭建电容成像实验装置(图2)进行实验研究,最后对比分析仿真结果(图3)与实验结果(图4)。 计算方法:通过 COMSOL Multiphysics® 软件的 AC/DC 模块,利用背对背三角形电容成像探头对不同深度的表面缺陷进行线扫描。求电容值仿真中用到了“静电(es)”接口,涉及到了基本的电磁学方程。 结果 ... Mehr lesen

Modeling Nanoscale Heat Flow

S. Palaich, and B. Daly
Physics and Astronomy Department, Vassar College, Poughkeepsie, NY, USA

When the dimensions of the material approach is a comparable size to the phonon mean free path, heat flow enters a new regime, the nanoscale. The Fourier and Cattaneo Equations describe bulk heat flow well, but radiative boundary terms must be considered when modeling nanoscale heat ... Mehr lesen

COMSOL Multiphysics Models for Teaching Chemical Engineering Fundamentals: Absorption Column Models and Illustration of the Two-Film Theory of Mass Transfer

W. Clark
Chemical Engineering Department, Worcester Polytechnic Institute, Worcester, MA, USA

COMSOL® models have been developed for teaching gas absorption fundamentals. Model results are compared to environmentally significant experimental results for removing CO2 and SO2 from air using water as solvent. For concentrated gas mixtures, the models are shown to be equivalent to ... Mehr lesen
