Figure 6.
The plot compares R e raised to minus 1 over 2 N u against xi. The horizontal axis is xi. The vertical axis is R e raised to minus 1 over 2 N u and ranges from minus 3 to 3. The legend states W e equals 0.5 for Williamson and equals 0.0 for Newtonian. Solid curves represent Williamson. Dashed curves represent Newtonian. The R i values are 0, 5, and 10. All curves begin slightly above 0 and rise gradually. The curves then oscillate with increasing amplitude as xi increases. The dashed curves show larger fluctuations near the right side, with some troughs reaching minus 3 and some peaks rising above 2. An arrow points upward through the curve group to mark the R i progression.Variations of We and Ri on Nusselt number
