摘要：

At a recent NSF-AFOSR workshop on self-sustaining mechanisms of wall turbulence several research groups presented their concepts This paper reviews the idea that were presented. The paper is to distribute this information to fluid dynamieists who are non specialist in turbulence. The production of turbulence and Reynolds stress centers around vortices and streaks of low speed fluid near the wall. There are two main categories of self-sustaining mechanisms. In one category parent vortices interact with the wall and produce offspring. In the second category streak velocity profiles are unstable and produce vortices.
