The plots below show profiles of the mean velocity and second moments (plotted against distance from the impingement wall) at a selection of radial locations for the $H/D=2$, $Re=23000$ case.

The plots below show profiles of the mean velocity and second moments (plotted against distance from the impingement wall) at a selection of radial locations for the $H/D=2$, $Re=70000$ case.

The plots below show profiles of the mean velocity and second moments (plotted against distance from the impingement wall) at a selection of radial locations for the $H/D=6$, $Re=70000$ case.

The plot below shows the distribution of Nusselt number along the impingement wall for all four cases.
