Figure 9.
The panel a shows n 25, with xi from 0 to 4 and Reynolds number to power negative one half times N u from about 0.25 to 1.0. The curves for alpha 0, 0.1, 0.5, and 0.9 begin near 0.64, decrease to about 0.33 near xi 0.7, then rise with oscillations to about 0.78 by xi 4. Panel b shows n 50, with the same axis ranges. The curves begin near 0.64, decrease to about 0.32 near xi 0.7, then rise with denser oscillations to about 0.75 by xi 4. Panel c shows n 75, with Reynolds number to power negative one half times N u from about 0.25 to 0.9. The curves begin near 0.64, decrease to about 0.33 near xi 0.7, then rise with dense oscillations to about 0.75 by xi 4.(a) Variations of on when n = 25, (b) Variations of on when n = 50, (c) Variations of on when n = 75
