Figure 7.
The panel a shows n is 5, with xi from 0 to 4 and Reynolds number to power one half times C f from 0 to above 30. The curves for alpha 0, 0.01, 0.05, and 0.1 begin near 14. The lowest variation stays around 14 to 15. The highest variation decreases to about 3 near xi 0.5, then oscillates between about 3 and 32. Panel b shows n is 10, with the curves beginning near 14. The lowest variation rises gradually to about 16. The highest variation decreases to about 3 near xi 0.5, then oscillates between about 3 and 32. Panel c shows n is 15, with the curves beginning near 14. The lowest variation rises gradually to about 16. The highest variation decreases to about 2 near xi 0.6, then oscillates between about 3 and 32, with closer oscillations after xi 2.(a) Effects of on when n = 5, (b) Effects of on when n = 10, (c) Effects of on when n = 15
