Fig. 2.17 Temporal variation of instantaneous V y (solid blue lines) on different heights of each
rectangular region with H = 8, 15, 30, 70d, and R = 0d. The V y of a randomly chosen individual
particle in the zone is shown with red dashed lines
Fig. 2.18 Time evolution of velocities of individual particles randomly chosen from the rectangular
zones with the centers (h, x)(h = 57, 70; x = 0, 28). Time-averaged velocity is shown with the gray
dashed line
