This model focuses on the direct modeling of Reynolds stresses and utilizes split-spectrum concepts to model multiple-scale effects in turbulence.

这种模型对雷诺应力进行直接的模拟，并可模拟湍流流动的多重尺度影响。

With the outer scale of turbulence increasing, the amplitude of low-frequency spectrum increases and the high-frequency is invariable.

随着等效湍流外尺度的增加，低频谱的幅值逐渐增大，高频谱保持不变。
