Abstract
It is disclosed the flow patterns of turbulent flows in near wall regi on by means of topological analysis. It has found that there exists a close relationship between the topological characteristics and the spi kes which are dominated by the strong normal velocity fluctuations nea r the wall. It is also shown that the dissipation of turbulent kinetic energy is closely related to the spike events.
