Turbulence statistics in an open rotor-stator configuration

Turbulence statistics, including complete budget data for the six individual components of the Reynolds stress tensor, have been compiled from a direct numerical simulation of the three-dimensional flow in an open rotor-stator configuration. Comparisons between turbulence statistics near the two disks and in plane Couette flow showed that the stator-side data closely resemble those found in Couette flow. At the rotor side rotational production terms due to the Coriolis force made only modest contributions to the budget equations for the Reynolds stresses, but the subtle influence of system rotation was by no means negligible.
