浸没在牛顿流体中的大系统重粒子的集体效应研究

On the collective effect of a large system of heavy particles immersed in a Newtonian fluid

Marco Bravin, Eduard Feireisl, Arnab Roy, Arghir Zarnescu

AI总结:

该研究针对有界域内牛顿流体中的大质量重粒子系统,分析半径趋于零、质量密度以适当速率趋于无穷的重粒子的集体效应,证明其与Navier-Stokes系统均匀化过程中的Brinkman摄动具有相似性。

摘要:

我们研究了占据有界空间区域的牛顿流体中大量重粒子的运动。此处“重”指粒子的质量密度在其半径趋于零时以适当速率趋于无穷大。我们证明,重粒子对流体运动的集体效应,与均匀化过程中识别出的Navier-Stokes系统的Brinkman摄动相似。

英文摘要:

We consider the motion of a large number of heavy particles in a Newtonian fluid occupying a bounded spatial domain. When we say "heavy", we mean a particle with a mass density that approaches infinity at an appropriate rate as its radius vanishes. We show that the collective effect of heavy particles on the fluid motion is similar to the Brinkman perturbation of the Navier-Stokes system identified in the homogenization process.
