Abstract
This paper presents the finite-difference solutions for a rotating disc flows system for the series of rotational Reynolds numbers Re_=5.5×105≤ Re_ ≤1.1×106 at a fixed value of mass flow rate Cw=2500. In order to assess the performance level of the closures, two turbulence models: the low Reynolds number k-ε model and low Reynolds number second moment closure are employed to predict the basic characteristics of rotating disc flow system. Predicted results revealed the profound effects of higher rotational Reynolds number on the stream lines and tangential velocity profiles, particularly in the source and sinks regions. The comparison of the two models shows that the low Reynolds number second moment closure produces a better agreement with the measurements in the central core region of the cavity.
