摘要：

A direct numerical simulation is combined with laboratory study to describe the turbulent flow in an annular high speed rotor-stator cavity. Comparisons are made for a turbulent flow characterized by a Reynolds number Re = Omega R-2(2)/v = 9.5 x 10(4) in a shrouded cavity of large aspect ratio G = (R-2 - R-1)/h = 18.32, where R-1 and R-2 are the inner and outer radii of the rotating disk, and h is the inter-disk space. A close agreement is found between the computed results and the experimental data for the mean and turbulent fields.
