Reviewer 2 Report
The presented research work introduces an improved modeling approach for the estimation of the temperature field in the proximity of hot oil pipes.
The methodology is explained rather well, the content could be quite of interest and, in general, it is a fair research work.
However, according to the reviewer, some points need to be clarified before stating that the manuscript is suitable for publication in Processes as listed here below:
- The main aspect that, in my opinion, needs to be clarified in order to meet the requirements to consider this research worth of publication is “why having a quicker prediction tool is important for this specific application?”. I understand that this methodology allows to considerably reduce the required computational time, however the authors should justify the reason behind the fact that the characteristic time of the previous approach is not suitable for this kind of calculation.
- What do you mean by “For the unsteady situation, the initial temperature field is required for the simulation, and a linear interpolation between Ta and Tc is adopted here.”? I’m not 100% sure to have correctly understood which temperature profile you used for your initial condition.
Minor remarks
- Due to the considerable amount of symbols and acronyms I suggest to include a dedicated section to resume and explain them;
- Please double check the manuscript for mistyping and format issues;
- Please pay attention to paragraph spacing, especially after equations (e.g. eq. 7, 10, 12);
- Part from 182 to 184 is not clear due to the presence of large parentheses with equation format in the middle of text parts. Please adjust it;
- A single table, or other graphic elements, should entirely fit in one page (e.g. Table 6). Please fix it.
