Figure 19.
The plot marks alpha equals 0.3 and n equals 1, 100, 200, 300. The horizontal axis is xi and ranges from 1.0 to 2.5. The vertical axis is R e raised to minus 1 over 2 N u and ranges from minus 2 to 6. The curves start near 1.5 at xi 1.0 and increase with small oscillations until about xi 1.8. The oscillations become larger after xi about 1.8. Peaks rise close to 6 near xi about 2.3 and 2.4. The final trough drops below minus 1 near xi 2.5. An arrow points from the n values toward the curve group near xi about 1.5.Impact of n on when = 0.4
