边界条件对三维Navier-Stokes流中接触问题的影响

The influence of boundary conditions on the contact problem in a 3D Navier-Stokes Flow

David Gérard-Varet, Matthieu Hillairet, Chao Wang

摘要:

本文考虑在粘性不可压缩流体中球体在壁面上方的自由下落。我们调查的边界条件的影响有限的时间发生的球和壁之间的接触。我们证明,滑移边界条件,使规避“无碰撞”的悖论与无滑移边界条件。我们还研究了混合边界条件的情况。

英文摘要:

We consider the free fall of a sphere above a wall in a viscous incompressible fluid. We investigate the influence of boundary conditions on the finite-time occurrence of contact between the sphere and the wall. We prove that slip boundary conditions enable to circumvent the "no-collision" paradox associated with no-slip boundary conditions. We also examine the case of mixed boundary conditions.
