In this model a Knowles ED23146 receiver (miniature loudspeaker) is connected to a test set-up consisting of a 50 mm (1 mm diameter) earmold tube and a so-called 0.4-cc coupler. The receiver is modeled using a lumped spice network and connected to the finite element domain at the tube ... 詳細を見る

This model illustrates the use of COMSOL Multiphysics for modeling of ionic current distribution problems in electrolytes, in this case in human tissue. The problem is exemplified on a pacemaker electrode, but it can be applied in electrochemical cells like fuel cells, batteries, ... 詳細を見る

この例では, 4C 放電中のバッテリパック内の温度分布をモデル化する方法を示します. パックは, まず2つの円筒電池を並列に接続して構成されます. 次に, 並列接続された6つのペアを直列に接続して, 完全なパックを作成します. (これは 6s2p 構成とも呼ばれます.) 問題の対称性は 2回使用されるため, 3つの電池の温度分布のみを解けば済みます. 適切な熱源を生成するために, 集中電池インターフェースの3つのインスタンスが使用され, その後, 3D ジオメトリ内の1つの伝熱インターフェースに結合されます. 詳細を見る

This example describes the pressure wave propagation in a muffler for an internal combustion engine. This example shows how to analyze both inductive and resistive damping in a muffler as well as the use of port boundary conditions. 詳細を見る

晶析は化学産業において重要な分離プロセスです. 医薬品や工業用化学品の製造に用いられています. また, 資源回収においても, 廃棄物から有用な物質を分離する方法として活用できます. このモデルは, 離散化ポピュレーションバランス方程式を解き, 0次元および3次元 T 型ミキサーにおける硫酸バリウムの沈殿から結晶粒度分布を求めます. 詳細を見る

This example demonstrates how to use a background field in a sound scattering problem. The application is an acoustic invisibility cloak made of a metamaterial. Two different types of metamaterials are used, one using an anisotropic acoustic material with varying properties and one using ... 詳細を見る

This example considers the natural convection of air above a smoldering incense stick. This kind of flow often shows a transition from laminar to turbulent which is nicely visualized by the smoke produced by the slow burning of the incense. The model uses the Nonisothermal Flow, LES RBVM ... 詳細を見る

This example models a small reverse osmosis water desalination unit. The unit consists of a spirally wound semi-permeable membrane through which the water is forced under high pressure. The membrane retains the salt, such that on the permeate side fresh water is produced and on the ... 詳細を見る

This tutorial example models the currents and the concentration of dissolved metal ions in a battery (corrosion cell) made from an orange and two metal nails. This type of battery is commonly used in chemistry lessons. Instead of an orange, lemons or potatoes can also be used. 詳細を見る

In a polymerization reactor for polyester manufacturing, the mixing in the reactor is achieved by impinging turbulent jets of reactants onto each other. The turbulence affects the reaction kinetics and quality of the polymer linkage. Turbulent flows involving rapid reaction kinetics are ... 詳細を見る
