We analyze steady motions of incompressible second- and third-grade fluids in an aperture domain. Such flows exist due to a pressure drop and provided the flux through the hole is small. We prove that the asymptotic behavior of their velocity field far from the aperture is of order |x|-2, which is the optimal result.

Abstract
We analyze steady motions of incompressible second- and third-grade fluids in an aperture domain. Such flows exist due to a pressure drop and provided the flux through the hole is small. We prove that the asymptotic behavior of their velocity field far from the aperture is of order |x|-2, which is the optimal result.File in questo prodotto:
