Large scale dynamics in a turbulent compressible rotor/stator cavity flow at high Reynolds number

The stability of the flow is governed by the boundary layers and is closely connected with that of a single infinite rotating disk.. The cross-flow instability appearing as

The effects of convective heat transfers on the turbulent air flow in an enclosed rotor- stator cavity are here investigated by large eddy simulation (LES) using the

The classical dynamic Smagorinsky model for the subgrid-scale stress (Germano et al. Numerical results include both instantaneous data and post-processed statistics. The results

The reduction of the structural parameter a 1 (the ratio of the magnitude of the shear stress vector to twice the turbulence kinetic energy) under the typical limit 0.15, as well as

In the first part of the paper, experimental results including mean radial and tangential velocity components, as well as three turbulent correlations, are presented for

Figure 2b reveals that the tangential velocity profile is divided into three distinct zones: the two boundary layers adjacent to the disks wall in which the axial gradients

Wu and Squires performed LES of the three- dimensional turbulent boundary layer over a free rotating disk at Re = 6.5 × 10 5 and in an otherwise quiescent in- compressible fluid

The present study focuses on the turbulent flow with separated boundary layers in a rotor-stator cavity with a low aspect ratio subjected to a weak centripetal radial
