Flow visualizations of 8-1-\(wTV{F}_{{H}_{x}}\). Flow visualization of flow states 8-1-\(wTV{F}_{{H}_{x}}\) at \({s}_{x}=0.6\) & \({s}_{z}=0.0\), \(R{e}_{i}=300\) in absence of axial through flow, i.e., \(Re=0\). Shown are: (1) isosurface of rv; (2) the azimuthal velocity \(v(r,\theta )\) within the 8-1-\(wTV{F}_{{H}_{x}}\) structure (a) and half system length apart (b); (3) vector plot \([u(r,z),w(r,z)]\) of the radial (u) and axial (u) velocity components including color-coded azimuthal vorticity \(\eta (r,\theta =0,z)\)); (4a–c) contours of the radial velocity \(u(r,\theta ,z)\) at different radial positions as indicated.
