通过对Wilcox的k-w湍流模型的改进，提高了对湍流流动的模拟质量。修改包括修正异常湍流能量的产生和改变，包括压缩性和旋转的影响。此外，块局部过渡模型，这是基于实验的相关性已经实现。最后，所提出的修改的性能被证明在工业航空设计中的应用程序相关的湍流流动。
An improvement of simulation quality of turbomachinery fluid flows has been achieved in upgrading the original k-w turbulence model by Wilcox. The modifications cover fixes for anomalous turbulent energy production and alterations to include the effects of compressibility and rotation. Furthermore, a block-local transition model which is based on experimental correlations has been implemented. Finally, the performance of modifications presented is demonstrated on turbomachinery flows which are relevant to applications in industrial aero design.
