Text Correction

There was an error in the original publication [1]. The sign in Equation (3) and above the equation has been misprinted.

A correction has been made to 3. Results and Discussion, Paragraphs 5 and 6:

After averaging over the temperature in the transverse direction in Equation (1) and using Condition (2), we obtain

\frac{\partial \bar{T}}{\partial t} = \frac{κ}{c_{p} ρ} \frac{\partial^{2} \bar{T}}{\partial z^{2}} - \frac{2 G}{R c_{p} ρ} (T (t, z, R) - T_{r o o m}) .

Assuming that the temperature changes across the fiber are insignificant and

\bar{T} (t, z) \approx T (t, z, R)

, which implies the relative smallness of the coefficient G, we obtain a one-dimensional equation for the temperature averaged over the transverse coordinate:

\frac{\partial \bar{T}}{\partial t} = \frac{κ}{c_{p} ρ} \frac{\partial^{2} \bar{T}}{\partial z^{2}} - \frac{2 G}{R c_{p} ρ} (\bar{T} - T_{r o o m}) .

The authors apologize for any inconvenience caused and state that the scientific conclusions are unaffected. This correction was approved by the Academic Editor. The original publication has also been updated.
