Abstract

Abstract

For the direct numerical simulation (DNS) of turbulent boundary layers,hou to generate an appropriate infow condition is problem that needs to be considered.Amethod was proposed,by which the infow condition for spatial-mode DNS of tolbulet boundary layers on supersonic blunt Cones with different Mach number,Reynolds number and wall temperature conditions can be generated,based only on a given instant flow field obtained by a temporal-mode DNS of a turulent boundary layer on a flat plate.the effectiveness of the proposed method is shown by three typical examples,thmugh comparing its results with those obtained by other methods.
- turulent boundary layer,
- direct nnunerical simulation (DNS),
- inflow condition blunt cone,
