摘要:
In this article we derive the no-slip boundary condition for a non-stationary vorticity equation. This condition generates the affine invariant manifold and no-slip integral relations on vorticity can be transferred to a Robin-type boundary condition. This condition leads to the appearance of the non-trivial kernel in Laplace operator and as result it causes the presence of the stationary solution of linearised equation. The no-slip condition causes an orthogonality of the flow to this kernel which is consistent with the Stokes Paradox.
