The 70°-delta-wing at AoA of 20° and Mach number of 0.55: a the normalized \({p}^{(1)}\)-field with iso-pressure lines, b \(\varvec{\tau}\)-lines overlaid on the \({p}^{(1)}\)-field, c near-wall streamlines, and d contours of the enstrophy near a wall. The freestream flow is aligned with the y-direction in the image plane. From Liu [31]
