Fig. 2.39 The transverse V x (a) and vertical V y (b) velocity on different streamlines obtained by
SAM and PTV. The particles were falling from the three inlet tube with the constant flow rates
(c). The average velocity field of V x . The dashed lines correspond to the flow rates of a. 45:60:45,
b. 35:80:35, d. 25:100:25, e. 14:122:14 pebbles per-minute from the left, center and right inlet tubes
respectively (d). The average velocity field of V y
