| 摘 要： | 研究了Gledzer-Ohkitani-Yamada模型中各种模型参数随外力的变化情况,计算了该模型充分发展湍流速度结构函数的相对标度指数随泰勒微尺度雷诺数的变化,计算结果既显示了与She-L啨vesque的速度结构函数标度律和实验结果的一致性,又给出了需要实验进一步检验的部分.

| Abstract: | In this paper,we study how the model parameters change with external forcing in Gledzer-Ohkitani-Yamada model.We calculate the changes of the Extended self-similarity of velocity structure function of fully intermittent turbulence with Taylor-microscale Reynolds number.Our results are not only consistent with the scaling of the She-Lévesque and experiment data but also need to be tested by experiment. |
