It can be seen in Table that the only temperature that differs -by more than 30 ℃ -is 𝑇 2 . In Appendix B it is shown that the AS of Peigné et al. does not satisfy -in general -the boundary condition for 𝑇 2 , at the inlet, which partly justifies this difference. It is important to note that in Figs. and, the results of the present AS for 𝑇 2 agree with our NS of the Peigné et al. model and with the results reported by Peigné et al. . However, as can be seen from Appendix B, the agreement in Fig. is not possible for 𝑇 2 , and Fig. correctly represents the results of these two analytical solutions. It is, therefore, concluded that the AS of Peigné et al. is -in general -incorrect for 𝑇 2 .
