A discussion on the convection parameters between the fluid and the liner as a function of pressure and speed should be added.  The lack of knowledge of these parameters must be significant, therefore it would be necessary to evaluate a probable scale of variation of this parameter and then to numerically quantify its impact on the spatial and temporal field in the tank. It is not possible to eliminate this analysis of data misunderstanding in the context of this article where the predictive character of the model is sought. No analysis is made on the wall speeds for the different configurations. It is an essential indicator for heat transfer between gas and solid.

I ask again the question: What is the consequence of this lack of knowledge on the result? I am not asking for a parametric study but to assess the risks of variability due to a lack of knowledge of the properties.  I would like to remind you that the purpose of the paper is to quantify the temperature fields to identify risks in terms of materials. Either the authors quantify the difference by different calculations or they discuss the lack of knowledge.
