| 英文摘要 | Besides gaussian self-similarity, there is non-gaussian self-similarity, i.e. a self-similar probability density function (pdf) is far away from gaussian. by using a non-gaussian pdf model of intermittent velocity increment, we study the non-gaussian self-similarity in kolmogorov's inertial range of hydrodynamic turbulence. in the limit of infinite reynolds number, a central part of scaling range becomes the inertial range, and we have a non-gaussian self-similarity in the inertial range. in scaling ranges at experimental reynolds numbers, the self-similarity is broken due to viscosity and large-scale effects. experimental facts of structure function exponents being anomalous, are not against the non-gaussian self-similarity in the inertial range. |
