SOME PROGRESS IN THE RESEARCH OF THE DYNAMICAL STRUCTURE IN WALL TURBULENCE
Four topics concerning the coherent structures of the turbulent boundary are discussed in this article. Firstly comments are given on the identification of CS (coherent structure), secondly some dynamical models of CS are surveyed, and thirdly a recent study of the fractal nature of CS is summarized and a close relationship between the burst and the fractility is clarified. Finally some preliminary discussions are presented concerning the application of Kullback-divergence to turbulent flow.
