Figure 4-14. Size of recirculation region as a function of K. The size is represented by the ratio
of area of recirculation region to the total area of the wavy channel. The wavy
channel is the same as in Figure 11, with h = 2.84 and a = 0.45. The labels (a-g)
correspond to the flow patterns in Figure 11, with K = 0 (a); K =1 (b); K= 1.1 (c); K
= 1.2 (d); K = 1.25 (e); K =2 (f); and K = 4.2 (g).
