Figure 21.
The plot lists 5 cases. Case 1 has phi sub 1 equals 0, phi sub 2 equals 0, phi sub 3 equals 0, and phi sub 4 equals 0. Case 2 has phi sub 1 equals 0.02, phi sub 2 equals 0, phi sub 3 equals 0, and phi sub 4 equals 0. Case 3 has phi sub 1 equals 0.02, phi sub 2 equals 0.02, phi sub 3 equals 0, and phi sub 4 equals 0. Case 4 has phi sub 1 equals 0.02, phi sub 2 equals 0.02, phi sub 3 equals 0.02, and phi sub 4 equals 0. Case 5 has phi sub 1 equals 0.02, phi sub 2 equals 0.02, phi sub 3 equals 0.02, and phi sub 4 equals 0.02. The horizontal axis is xi and ranges from 0.5 to 2.0. The vertical axis is R e raised to 1 over 2 C f and ranges from about 0 to above 30. The curves start near 0 at xi 0.5 and rise with repeated peaks and troughs. The peaks increase toward xi 2.0. An arrow points from the case numbers toward the curve group near xi about 1.2.Variations of on
