摘 要:
研究了Gledzer-ohkitani-Yamada(或GOY)模型的阵发湍流.通过相平面分析方法研究了惯性区各壳相空间的轨道,发现阵发轨道部分的随机性导致不稳定准周期轨道的随机转动、反转和锁定现象.计算了阵发轨道扩展自相似标度律,指出阵发性能量传递方式是导致反常标度的原因.[著者文摘]

Abstract:
In this paper, intermittent turbulence in Gledzer- Ohkitani -Yamada model is investigated. Orbits in each shell phase space are discussed through phase space analysis. It is found that the random wandering of intermittent orbit parts leads to the random rotation, counter rotation and lock of unstable quasi - periodic orbit part position around stable fixed point. It is calculated the extended self - similarity of intermittent turbulence and pointed out that nonlinear scale law in initial - range is decided by intermittent energy transmission.[著者文摘]
Key words:
intermittency ; chaos ; inertial range ; extended self - similarity (ESS)
