球体与涂有液膜的壁面的碰撞

Collision of a sphere onto a wall coated with a liquid film

A. M. Ardekani, R. H. Rangel

摘要:

颗粒-颗粒和颗粒-壁碰撞发生在许多自然和工业应用中,如沉降、团聚和颗粒流。为了准确地预测颗粒流的行为,需要单个碰撞机制的基本知识。在这个流体动力学视频中,显示了颗粒与壁面碰撞到涂有1.5%聚(环氧乙烷)(PEO)(粘弹性液体)和80%甘油和水(牛顿液体)的壁上。

英文摘要:

Particle-particle and particle-wall collisions occur in many natural and industrial applications such as sedimentation, agglomeration, and granular flows. To accurately predict the behavior of particulate flows, fundamental knowledge of the mechanisms of a single collision is required. In this fluid dynamics video, particle-wall collisions onto a wall coated with 1.5% poly(ethylene-oxide) (PEO) (viscoelastic liquid) and 80% Glycerol and water (Newtonian liquid) are shown.
