ON EVOLUTION OF TURBULENT SPOTS WITH INITIAL MULTIPLE DISTURBANCE MODES
Keyword(s):
The formation and nonlinear evolution of turbulent spots in the near wall shear flow are researched by the direct numerical simulation of Navier-Stokes equations, and the initial multiple disturbance models with the pulse form are proposed. A group of three-dimensional coupling difference schemes with high accuracy and resolution are used to simulate evolution processes of turbulent spots, and the computed results show clearly basic characteristic of turbulent spots, specially, interaction properties between turbulent spots.
