This thermo-hydro-mechanical (THM) model of artificial ground freezing couples heat transfer, groundwater flow, and soil mechanics to capture ice formation, pore-pressure changes, and ground deformation during tunnel excavation. The freezing process is modeled with the apparent heat ... 詳細を見る

この例では, 水で満たされた貯水池の上に置かれた細い垂直シリンダーを調べます. 空気と水の界面の壁面接着と表面張力により, 水は流路を通って上昇します. 表面張力と壁面接着力は, MEMS デバイスのマイクロ流路を通じて流体を輸送したり, マイクロピペットを使用して少量の流体を測定, 輸送, 配置したりするためによく使用されます. 多孔質媒体を通る多相流や固体壁上の液滴も, 壁面接着力と表面張力が流れのダイナミクスに強く影響する例です. 壁面の接着力を正しくモデル化するには, 境界条件の扱いが重要です. 壁面の速度をゼロに固定すると, ... 詳細を見る

This model shows how to compute an array of borehole heat exchangers (BHEs) for shallow geothermal energy production. The BHEs are simplified as line heat sinks with a uniform heat extraction rate. The array is embedded into a layered subsurface model with groundwater flow in one of the ... 詳細を見る

This application uses the shrinking core model to study the reduction of iron ore pellets. A 1D model of a packed bed containing iron ore pellets is modeled. The bed filling pellets initially consists of solid phase FeO. The pellets are reduced by CO, and the solid core shrinks leaving a ... 詳細を見る

This case shows how to simulate moisture transport in a homogeneous wall under isothermal conditions. With this assumption, an analytical solution can be calculated. The homogeneous layer is initialized in moisture balance. At the beginning of the simulation, the relative humidity of ... 詳細を見る

This is a template base model containing the physics, geometry and mesh of a lithium-ion battery, defined in 1D. The model makes use of four lithiation parameters which are used to define the relative balancing of the negative and positive electrodes, as well as global cell state of ... 詳細を見る

Atmospheric corrosion occurs when metallic structures are exposed to humid air forming a thin electrolyte film in the range of up to a few hundred micrometers. The model presented here accounts for charge transport as well mass transport involving 10 species and 6 homogeneous ... 詳細を見る

The goal with this app is to explain experimental electrochemical impedance spectroscopy (EIS) measurements and to show how you can use a simulation app, along with measurements, to estimate the properties of lithium-ion batteries. The app takes measurements from an EIS experiment and ... 詳細を見る

Mass transport limitations within thin crevices can often result in the local electrochemistry to differ significantly between the crevice opening (mouth) and end (tip), and as a result of the differences in local chemistry, corrosion may occur. This example models crevice corrosion of ... 詳細を見る

This example models the flow and mass transport in the channels and the gas diffusion layer (GDL) of a polymer electrolyte fuel cell. The cathode electrode reaction is modeled as a boundary condition, where the local current density depends on the overpotential and the local oxygen ... 詳細を見る
