Abstract: The rotating terms in Reynolds stress equations (RSEs) are analyzed , and the appropriate modellings to these terms are proposed in this paper. By means of the local equlibrium of turbulence production, dissipation and rotating terms, an nonisotropic three-dimensional turbulence model which contains the rotational vector are proposed. This model is appropriate to mild three-dimensional shear flows. Calculations are done with this model on a rotational helical blade and a compressor rotor blade, the results art: comparied with experiments and the computation results with C-S model, showing that the present model can improve the prediction capability of near wall parameters in certain extent. Otherwise, this model is simple and can be considered as the extention of Brad-shaw's model in three-dimensional flows.
Key words: three-dimensional boundary, turlmtont modell, rotating fluids
