Large axisymmetric surface deformation and dewetting in the flow above a rotating disk in a cylindrical tank: Spin-up and permanent regimes

Year: 2020

Type: article

Abstract: Accurate measurements and axisymmetric numerical simulations of the spin-up of a fluid driven by a rotating disk are carried out. In particular, disk dewetting is taken into account. This constitutes a solid benchmark and paves the way for future numerical investigations on the three-dimensional regime of rotating polygons, for example.
