アルカリ水電解は, 水素ガスを生成するための確立された工業プロセスです. セル内では, 陰極で水素ガスが, 陽極で酸素ガスが生成されます. 電解液は水溶液であり, 発生したガスが泡状になると, 実効イオン伝導率が低下します. また, 発生したガスは, 電極反応がアクセス可能な表面積を減少させることから, セルの性能に悪影響を及ぼす可能性があります. この例では, ガス生成がアルカリ電解セルの性能に与える影響を調査します. 詳細を見る

An Einzel lens is an electrostatic device used for focusing charged particle beams. It may be found in cathode ray tubes, ion beam and electron beam experiments, and ion propulsion systems. This particular model consists of three axially aligned cylinders. The outer cylinders are ... 詳細を見る

At the resonance frequency, the capacitive coupling between the turns causes the impedance of a coil to transition from inductive to capacitive. This application analyzes the resonance of a 5 turn spiral coil of copper equipped with a thin epoxy varnish insulation layer. The capacitive ... 詳細を見る

This example shows how to set up a piezoelectric transducer problem following the work of Y. Kagawa and T. Yamabuchi. The composite piezoelectric ultrasonic transducer has a cylindrical geometry that consists of a piezoceramic layer, two aluminum layers, and two adhesive layers. The ... 詳細を見る

This model presents two examples of topology optimization of the magnetic circuit of a loudspeaker driver. A first optimization is used to find the design of a nonlinear iron pole piece and top plate that maximize the BL factor at the resting position (small displacements), while ... 詳細を見る

Pitting corrosion is a type of localized corrosion by which local cavities, pits, are formed on an initially smooth metal surface. A pit may be initialized by surface defects, such as an inhomogeneities in composition or shape, or mechanical abuse resulting in a small scratch or dent. ... 詳細を見る

In this model, a turbocharger supported on two floating ring bearings is studied. The film forces on the ring cause it to rotate within the bearing. In steady state, the ring rotates at a constant angular speed and the torque on the ring due to the inner and outer films are balanced. ... 詳細を見る

This example models the deposition of an inductor coil in 3D. The geometry includes the extrusion of the deposition pattern into an isolating photoresist mask, and a diffusion layer on top of the photoresist. The mass transfer of copper ions in the electrolyte has a major impact on the ... 詳細を見る

真空乾燥は, 製薬業界や食品業界で, 湿った粉末から水や有機溶媒を除去するために頻繁に用いられる化学プロセスです. 真空乾燥システムを設計する際, エンジニアは製品の品質を高く維持しながら乾燥時間を最小限に抑えることを目指します. このモデルは, Nutsche 式フィルタードライヤーにおける真空乾燥を調査します. Nutsche 式フィルタードライヤーは, 湿ったケーキが充填された円筒形のドラムで構成されています. ケーキの上部は低圧のヘッドスペースにさらされ, 側壁と底壁は加熱流体にさらされます. 非常に低い圧力と高温で動作させることで, 液体の蒸発速度が増加し, ... 詳細を見る

The magnets in an Interior Permanent Magnet (IPM) motor are embedded in the rotor core, where they form narrow regions known as bridges. The thickness of the magnetic bridge is an important parameter to consider in design, both from the electromagnetic and the mechanical perspectives. As ... 詳細を見る
