The plots below show streamlines for a selection of step angles and channel expansion ratios, at Reynolds number of \(Re_H=15000\).

The plots below show profiles of the mean and rms streamwise velocity at selected streamwise locations for the channel expansion ratio of \(1.48\), \(Re_H=47000\) and step angle of \(90^o\).
