Figure 8.
The panel a shows alpha 0.01, with xi from 0 to 4 and Reynolds number to power one half times C f from about 12.5 to 17. The curves for n 1, 5, 10, 15, and 20 begin near 13.5, dip to about 12.5 to 13.5, then oscillate with increasing frequency and rise to about 17 by xi 4. Panel b shows alpha 0.05, with values from about 6 to 24. The curves begin near 14, dip to about 7.5 to 9, then oscillate between about 8 and 23. Panel c shows alpha 0.1, with values from about 0 to 35. The curves begin near 14, dip to about 2 to 4, then oscillate between about 3 and 33, with closer oscillations after xi 2.(a) Effects of n on when =0.01, (b) Variations of n on when = 0.05, (c) Variations of n on when = 0.1
