This model deals with electrohydrodynamics (EHD), where a charge separation on the phase boundary between a liquid and air involves the formation of a charged layer. This charged layer allows for a net force to be induced at the interphase when a large electric field is applied. The ... 詳細を見る

Although initially invented to be used in printers, inkjets have been adopted for other application areas, such as within the life sciences and microelectronics. Simulations can be useful to improve the understanding of the fluid flow and to predict the optimal design of an inkjet for a ... 詳細を見る

The Marangoni effect results in a slip velocity in the tangential direction on a fluid/fluid interface due to gradients in the surface tension coefficient. When the surface tension coefficient is constant, a two-fluid system may exist in static equilibrium. This is because the surface ... 詳細を見る

Emulsions consist of small liquid droplets immersed in an immiscible liquid and widely occur in the production of food, cosmetics, fine chemicals, and pharmaceutical products. The quality of the product is typically dependent on the size of the droplets. Simulating these processes can ... 詳細を見る

Applying an electric field across a suspension of immiscible liquids may stimulate droplets of the same phase to coalesce. The method known as electrocoalescence has important applications, for instance, in the separation of oil from water. To model electrocoalescence, you need to solve ... 詳細を見る

This tutorial shows how to set up a 3D simulation of rubber injection molding. A phase field method is used to track the interface between the rubber and the displaced air. The rubber is modeled as shear-thinning inelastic non-Newtonian power law fluid with a fluid-consistency ... 詳細を見る

This model shows modeling of a sphere falling on a water surface. Specifically, it models the oscillating motion of a buoyant sphere as it falls through air and interacts with the air-water interface to finally float on water. Get more details in our blog post: Modeling a Sphere Falling ... 詳細を見る

This example simulates an oil droplet rising through a suspension. The suspension is initially stratified, with a dense layer between two clear layers. The droplet is initially located in the bottom clear layer. The particles in the suspension start to sediment toward the bottom of the ... 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 example of turbulent flow in a partially baffled turbulent mixer with a three-bladed impeller shows how to set up the Rotating Machinery, Turbulent Flow interfaces from the Mixer Module with a Level Set method for free surface flow in a rotating geometry. A time-dependent simulation ... 詳細を見る
