Figure 8 Scalar species passage through a narrowing pylorus (Re = 333): t = 2. 5 time units; the pyloric lumen is occluded and inlet velocity has returned to 0.0. The thin, high velocity jet affected by the narrow lumen has led to rapid growth of a strong vortex pair, which sheds and propagates downstream as the bulk flow is halted.
