Dialysis is a widely used chemical species separation method. One such example is hemodialysis, which acts as artificial kidneys for people with renal failure. In dialysis, only specific components are allowed to diffuse through the membrane, based on differences in molecular size and ... 詳細を見る

This benchmark model computes the transient pressure distribution and film height in a squeeze film bearing for lubrication in a nonconformal conjunction of a solid sphere and an elastic wall separated by a lubricant film. This model solves the benchmark case of hydrodynamic interaction ... 詳細を見る

このモデル例では, 空冷式円筒型 18650 リチウムイオン電池の充放電サイクルとそれに続く緩和期間をシミュレートします. 電池セルの化学組成をモデル化するために集中型 (0次元) セルモデルを使用し, 電池内部の温度をモデル化するために2次元軸対称モデルを使用します. 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

In this shape optimization example, the mass of a bracket is minimized by changing the size and position of a number of geometrical objects. The requirements give limits both on the lowest natural frequency, and on the maximum stress in a static load case. This means that results from ... 詳細を見る

Helmholtz resonators are used in exhaust systems, as they can attenuate a specific narrow frequency band. The presence of a flow in the system alters the acoustic properties of the resonator and the transmission loss of the subsystem. In this tutorial model, a Helmholtz resonator is ... 詳細を見る

This example solves the heat transfer in an isothermal box aimed at transporting refrigerated articles such as medical materials for 24 hours. In this case, the box has to keep the contents cold for a long period of time while respecting storage temperature restrictions between 2°C and 8 ... 詳細を見る

Impedance tubes are used for estimating the surface impedance of various samples, for example, a layer of porous material used for sound insulation. This model shows how the five material parameters of the Johnson-Champoux-Allard model can be estimated from the pressure at two ... 詳細を見る

This benchmark model computes the total force acting on a vibrating disc in the frequency and time domains and compares both results with expressions derived analytically. When the vibration amplitude is small enough that the system is linear the frequency and time domain results agree ... 詳細を見る

Homogeneous Charge Compression Ignition (HCCI) engines are being considered as an alternative to traditional spark- and compression-ignition engines. As the name implies, a homogeneous fuel/oxidant mixture is auto-ignited by compression with simultaneous combustion occurring throughout ... 詳細を見る
