充分发展的turbulence的各向异性和不对称性
Anisotropy and asymmetry in fully developed turbulence
摘要:
本文利用高雷诺数湍流的纵向和横向速度实验数据,研究了湍流的各向异性和非对称性。这两种现象似乎都与小尺度湍流结构和湍流度有关。我们可以假设,大尺度速度切变对小尺度湍流产生了冲击,导致了非定域性和相关的异常事件。
英文摘要:
Using experimental longitudinal and transverse velocities data for very high Reynolds number turbulence, we study both anisotropy and asymmetry of turbulence. These both seem to be related to small scale turbulent structures, and to intermittency. We may assume that the large scale velocity shear gives an impact into the small scale turbulence, resulting in non-locality, and related anomalous events.
