Figure 18.
The horizontal axis gives xi from 0 to 4, and the vertical axis gives Reynolds number to power negative one half times N u from 0.3 to 1.1. The curves for S 3, 3.7, 4.9, 5.7, and 8.6 decrease to about 0.34 to 0.46 near xi 0.6, then increase with small oscillations. At xi 4, the values range from about 0.78 to 1.1, with higher S values giving higher curves.Impact of Sphericities on
