Research on statistic characteristic of near-wall turbulence

  • 摘要: 采用大涡模拟方法,模拟了槽道湍流,得到了不同雷诺数下槽道湍流的结果. 在此基础上,研究了平均速度、雷诺应力、脉动动能和脉动速度均方根的分布;讨论了平均速度的壁面律问题;给出了雷诺应力、脉动动能和脉动速度均方根随雷诺数的变化规律,其中雷诺应力、脉动动能给出了定量公式.
    Abstract: Channel turbulence is simulated by large eddy simulation(LES), and turbulent databases of channel flows at different Reynoldsnumbers are established. Then, the mean velocity distribution, Reynoldsstress and root-mean-square (RMS) velocity distribution are obtained.Furthermore the problem of the wall law is discussed. Meanwhile, a rule ofReynolds stress, energy of velocity fluctuations and RMS velocity withdifferent Reynolds number is presented along with quantitative formula.
