Fig. 3.

(a) Normalized mean axial velocity profiles ($\overline{u}/U_m$) at indicated locations along the axial direction. Solid lines correspond to WenoHemo simulation, solid dots indicate DNS [9]. Scale represents 1 axial unit (x/D) equals 5 velocity units $(\overline{u}/U_m)$. (b) Contours of normalized vorticity magnitude ($\left|\overrightarrow{\omega }\right|D/U_m$) on XY-plane at Z = 0.
