Primary flow. Figure 1A (1D) - symmetry preserving (breaking) grooves; Fig. 1B (1E) - contour plot of the streamwise velocity for the symmetry preserving (symmetry breaking) grooves for \(S=0.4,\alpha =1\) (S = 0.8, α = 0.8). Grey color identifies zones of accelerated fluids. Figure 1C (1 F) - variations of the flow rate as a function of S and \(\alpha \) for the symmetry preserving (symmetry breaking) grooves. Grey color identifies drag reducing configurations. Q (Qr) stands for the flow rate of the modified (unmodified) flow driven by the same pressure gradient.
