| 内容記述 | Recent new findings concerning turbulent structure in wall turbulence are reviewed. The review is composed of two sections devoted to near-wall turbulence and outer layer turbulence, respectively. In the former, topics on the elementary vortices which are key player in the layer close to the wall, for the sake of a locally low Reynolds number there, are described. Turbulent-like but steady laminar flows including streamwise vortices are shown to occur between normal laminar and turbulent regime. As for the outer layer structure, it is suggested that cross-stream vortices having their axe in spanwise direction play dominant role in boundary layer flow, while streamwise large-scale vortices are dominant in channel/pipe flows. Lower capability of mixing of the spanwise vortices than streamwise ones causes wake-like property in the outer layer of boundary layer flow, which reasonably explains other particular features of turbulence observed there. | |||||
