This paper solves the three-dimensional Navier-Stokes equation by a fractional-step method with the Reynolds number Reτ=194 and the rotation number Nτ=0-0.12. When Nτ is less than 0.06, the turbulence statistics relevant to the spanwise velocity fluctuation are enhanced, but other statistics are suppressed. When Nτ is larger than 0.06, all the turbulence statistics decrease significantly. Reynolds stress budgets elucidate that turbulence kinetic energy in the vertical direction is transferred into the streamwise and spanwise directions. The flow structures exhibit that the bursting processes near the bottom wall are ejected toward the free surface. Evident change of near-surface streak structures of the velocity fluctuations are revealed.  相似文献

教学期刊论文的情况是教学情况的一种反映.国内外的物理教育研究期刊分别为《物理教学》、《大学物理》、Physics Education,The Physics Teacher和American Journal of Physics.文章利用物理教学期刊论文,分别从论文的形式(前言、摘要和参考文献)和内容两方面对中国与国际的物理教育研究与发展开展了初步的比较研究,通过利用教育理论对统计资料的解释初步揭示了国内外物理教育研究的差距,为它们的进一步发展提供了启发性和指导性的建议.  相似文献

Intensive blue photoluminescence (PL) was observed at room temperature from the nanocrystalline-Si/SiO2 (nc-Si/SiO2) multilayers (MLs) obtained by thermal annealing of SiO/SiO2 MLs for the first time. By controlling the size of nc-Si formed in SiO sublayer from 3.5 to 1.5 nm, the PL peak blueshifts from 457 to 411 nm. Combining the analysis of TEM, Raman and absorption measurement, this paper attributes the blue PL to multiple luminescent centres at the interface of nc-Si and SiO2.  相似文献
