ABSTRAKT

This paper describes further developments of a near-wall second moment turbulence closure of Manceau and Hanjalic(2002), and its application to the imposed system rotation. To refine the model, called "the elliptic blending model", an inhomogeneity correction is added to the near-wall redistribution term. Also, another approach to modelling the near-wall limiting redistribution is employed for the general complex geometries, which frequently appears in industrial applications. Concerning the homogeneous redistribution, the model of Speziale-Sarkar-Gatski(SSG) is replaced by a Launder-Tselepidakis non-linear model. The present refined model is tested by direct comparison with the DNS to validate the performance of predictions.
