Effects of Peclet Number of Dopant Y. Yan and R. Pitchumani, Int. J. Heat and Mass Transfer (2006)
The surface temperature is independent of Pe, due to the model assumption.

As Pe increases, centerline dopant concentration decays less along the axis (due to poor diffusion), and the refractive index varies considerably across the radius. The results suggest that refractive index profile may be tailored to a degree through processing conditions (in addition to material choices)
