Large Eddy Simulation Of Turbulent Channel Flow With Suction On The Wall

Large-Eddy Simulation was used to simulate the turbulent channel flow withperiod suction on the wall. High order compact finite difference scheme and Fouriertransformation were also adopted in our method. The third order mixed explicit-implicitscheme was employed for the time discretization. Large scale structure was calculatedfrom the Navier-Stokes equation. The small scale structure was simulated separately byfour Sub-Grid-Stress Models in this paper, while the boundary function was introducedin Smagorinsky Model. The distribution of Reynolds Stress, the Mean Rate of Strainand the phase distribution of Reynolds Stress and the Mean Rate of Strain wereobtained. These results were coincide with those of Direct Numerical Simulation.Meanwhile, the effects on simulation of different Sub-Grid-Stress Models werediscussed in detail.
