二维不可压缩理想流体中小物体的运动

On the motion of a small body immersed in a two dimensional incompressible perfect fluid

Olivier Glass, Christophe Lacave, Franck Sueur

摘要:

本文证明了二维不可压缩理想流体中固体的运动,当固体收缩到一个具有固定质量和环量的点时,收敛到涡波系统的一个变形,在这个变形中,位于收缩体所占据的点上的涡被一个类似于无旋理论中的Kutta-Joukowski力的升力加速。

英文摘要:

In this paper we prove that the motion of a solid body in a two dimensional incompressible perfect fluid converges, when the body shrinks to a point with fixed mass and circulation, to a variant of the vortex-wave system where the vortex, placed in the point occupied by the shrunk body, is accelerated by a lift force similar to the Kutta-Joukowski force of the irrotational theory.
