As stated in the present research, the anisotropic non-Kolmogorov turbulence model is more in line with the actual turbulence. However, anisotropic factor is vital for the accuracy of calculations, and measuring it precisely is a challenging task. In this paper, utilizing three modeling approaches, we derive four different equivalence formulas between the anisotropic non-Kolmogorov and the Kolmogorov structure constants, and apply them to the extant anisotropic results. It is found that the anisotropic factor is eliminated and the anisotropic turbulence can be predicted only by Kolmogorov structure constant and power law.

一个新的想法:仅通过Kolmogorov结构常数来计算各向异性湍流 Cñ2 和幂律 α

如本研究所述,各向异性非Kolmogorov湍流模型更符合实际湍流。但是,各向异性因子对于计算的准确性至关重要,而精确地进行测量是一项艰巨的任务。在本文中,利用三种建模方法,我们得出了各向异性非Kolmogorov和Kolmogorov结构常数之间的四个不同的等价公式,并将它们应用于现有的各向异性结果。发现消除了各向异性因素,仅通过Kolmogorov结构常数和幂定律可以预测各向异性湍流。
