Implicit Large-Eddy Simulations of Wall-Bounded Turbulent Flows.

摘要

The paper presents application of Implicit Large Eddy Simulation(ILES)to wall-bounded turbulent flows. A characteristics-based scheme in conjunction withtotal variation diminishing(TVD)Runge-Kutta time stepping and slope-limitingvariants,for the com-pressible flow case, have been employed. Results are pre-sented for an incompressible lid-driven cavity flow,using an incompressiblesolver, and low-Mach number flows over a hill and around a delta wing, using acompressible solver. Good agreement with experimental data and numerical resultsusing classical LES has been obtained. Future ILES developments are alsodiscussed
