in turbulent shear stress and drag, possibly due to the misalignment of turbulent structures.
However, little is known about the impact of flow skewing in turbulent shear layers. Using direct
numerical simulations (DNS), the current study is aimed at investigating the qualitative and
quantitative effects of three-dimensionality in incompressible shear layers. Further, a range of “what if?”
numerical experiments will be performed to isolate the effects of skew in mean flow and
turbulent fluctuations.
