The plots below show profiles of the mean \(U\) velocity, and rms \(u'\) and \(v'\) velocities at a selection of streamwise locations through the tube bundle for the staggered \(3.6\times 1.6\) case.

The plots below show profiles of the mean \(U\) velocity, and rms \(u'\) and \(v'\) velocities at a selection of streamwise locations through the tube bundle for the staggered \(3.6\times 2.1\) case.
