Abstract

Turbulent boundary layers (TBLs) under the effect of an adverse pressure gradient (APG) are significantly different from canonical wall-bounded flows because of the increasing momentum deficit. In this study, the effect of velocity defect on energy-transferring structures is investigated in a non-equilibrium APG TBL with Reθ reaching 8000. The spectral distributions of production and pressure-strain of ⟨ u2⟩ have been employed. The findings show that energy-transferring structures in APG TBLs may remain fairly similar within one layer (inner or outer) as the defect increases.
