Overview of recycling-rescaling method for inflow boundary conditions of LES and DNS of compressible wall bounded turbulent flows

The inflow turbulent fluctuating boundary conditions play a key role in large eddy or direct numerical simulations of many turbulent problems.This paper introduced a method—recycling-rescaling method for inflow fluctuation generation of compressible wall bounded turbulent flows.The theory foundation and deduction of the method were given in the paper.Several recycling-rescaling methods were introduced and some key points in the implementation were indicated.Applications were summarized and limitations were discussed.This paper can be a reference for further investigation in LES(large eddy simulation) and DNS(direct numerical simulation) of turbulent flow and combustion problems.
