607 Reynolds Number Dependence of Turbulence structure in Temporally Developing Turbulent Mixing Layers
Details
To clarify the Reynolds number dependencies of turbulence structure in turbulent mixing layer, direct numerical simulations of temporally developing turbulent mixing layers up to Re_<ω,0>=700 are conducted. 0n the occasion of transition to turbulence, many fine scale eddies appear in turbulent mixing layer. The number of the fine scale eddies increases and the spatial distribution of the eddies becomes non-uniform at high Reynolds number. The large scale structure which consists of many fine scale eddies makes large contribution to total energy dissipation in the fully-developed stage.
