Abstract

Numerical simulations and measurements using PIV and LDV have been carried out for steady vortex breakdown inside a closed container. The numerical solution has been employed as a benchmark to assess the capabilities and limitations of the experimental techniques in a difficult flow case involving a double breakdown in the limit of the steady regime.
