The high order compact d if ference method is developed for solving the perturbation equations based on Navi er Stokes equations, and is used in studying complex evolution processes from w all negative pulse to the turbulent coherent structure in the channel flow. Th is method contains three dimensional coupling difference scheme with high accur acy and high resolution, and the high order time splitting methods. Compared with the general spectral method, the method can be used to research turbule nt coherent structure under more general boundary conditions and in flow domains . In this paper, the generation and evolution of the turbulent coherent structur es ind uced by wall pulse in the channel flow are simulated, and the basic characterist ics and rules of the turbulent coherent structure are shown. Computational r esults indicate that a wall negative pulse is more convenient than the resonant three wave model.

The Navier-Stokes equations are used to simulate forming and evolution of the turbulent spot in the channel flow. The high-order compact difference schemes are constructed by the high-order and high-resolution three-dimensional coupling centric difference schemes combined with the time-splitting method and high-order upwind scheme. This method can be used in the all computational area including in the vicinity of the boundary, in which general high-order centric difference scheme can't be applied. In the boundary the nonreflect and pressure conditions are satisfied, and accuracy and consistent of schemes are ensured. The evolution process from wall pulse to turbulent spots in the channel flow are simulated directly. The results show the basic characteristics of the turbulent spots including Reynolds stress , velocity and pressure impulse, and indicate that the forming of the turbulent spot is dependent on intensity of wall pulse and Reynolds number.
