このモデルは, COMSOL Multiphysics を使用して, 異なる次元で定義された現象を完全に連成した方法でモデル化する方法を示しています. ほとんどの場合, 反応速度式は反応物と生成物の濃度の関数として定義されますが, 吸着反応では活性部位または表面複合体の表面濃度もモデル化する必要があります. これは, リアクターのバルク内の質量バランスを, デバイスの表面のみに存在する種の質量バランスと結合する必要があることを意味します. このデバイスは, 触媒, バイオチップ, 半導体部品, または表面固有の化学種を含む任意のプロセスである可能性があります. ... 詳細を見る

Electronic equipment often has to be certified to function after having been subjected to a specified shock load. In this example, the effect of an 50g 11ms half sine shock on a circuit board is investigated using response spectrum analysis. The results are compared with a time domain ... 詳細を見る

This tutorial demonstrates a structural analysis of a simple telescope. The deformation of the telescope structure under gravity is examined and the effect on image quality is demonstrated. 詳細を見る

This tutorial presents a study of positive and negative corona discharges in dry air at atmospheric pressure. The discharges are sustained within two electrodes in a coaxial configuration by a high voltage DC source applied to the inner electrode. Two different types of models are used: ... 詳細を見る

This model defines a zero-gap alkaline water electrolyzer, where oxygen and hydrogen gas are evolved in porous gas diffusion nickel felt electrodes, placed adjacent to a porous separator (diaphragm). The geometry defines a unit cell of an electrolyzer stack, in turn comprising two full ... 詳細を見る

This tutorial demonstrates how to compute the periodic steady-state solution of a nonlinear model problem using an optimization solver. The solver modifies the initial conditions at the beginning of a period to match the solution at the end of the period. The model solves much faster ... 詳細を見る

This example studies heat transfer in a square column. Cold and hot temperature conditions are applied to the boundaries. Due to the symmetry of the problem, the geometry is simplified to half of the square. The temperature field is compared with the analytic data. This example ... 詳細を見る

Striking a drum excites a spectrum of vibration modes that together make up the instrument’s characteristic sound or acoustic signal. These vibration modes correspond to the eigenmodes, or eigenfunctions, of the drum’s membrane. Thus you can study this problem by solving eigenvalue ... 詳細を見る

This model simulates a 16-level, first-order, focusing Fresnel lens with 50 µm diameter and 150 µm focal length. In one simulation, the Electromagnetic Waves, Frequency Domain interface computes the electric field in the Fresnel lens and the surrounding air domain extended to the focal ... 詳細を見る
