Large eddy simulation of an equilibrium three-dimensional turbulent boundary layer

摘要

large eddy simulation has been applied to prediction of an equilibrium three-dimensional turbulent boundary layer (TBL). Subgrid-scale stresses were parameterized using a Lagrangian dynamic mixed model. The predicted mean velocities an second-order statistics are in good agreement with direct numerical simulation results. Single- point statistics are also generally similar to those found in other equilibrium three-dimensional TBLs such as the flow over a rotating disk and the turbulent Ekman layer.
