Validity, Verifiability, and Confirmability: A Critique of Multiphase Packed Bed Modeling

Round 1

Reviewer 1 Report

Comments and Suggestions for Authors

While the MS deals with an interesting topic, some comments should be addressed before its publication.

The background study is not sufficient. It is expected to be rewritten using relevant and recent works rather than outdated references.

The novelty should be highlighted.

All equations should be cited.

In the result section, justification and discussion should be validated with at least one recent work.

Reviewer 2 Report

Comments and Suggestions for Authors

This is an interesting topic, and an important one. Modelling of packed bed systems is widespread nowadays and there are a number of different modelling approaches, tools and techniques employed.

Introduction is inspiring but I feel the number of reference sources can be improved. Please avoid grouped references (for example, page 2, row 36).

I don't believe the content/length of section 3 justifies it being a stand alone section. 

In section 4, can you please explain why these two data sets were used/how were they selected and what is the significance?

On page 9, can you please explain Model B and how it is different to Model A?

On Page 10, rows 270-271: "... Model B is not supported by experimental data. Even then, validity cannot be claimed." Could you please explain where the data in Table 2 originates from? Moreover, when would you say validity can be claimed?

I am struggling to see the point in section 4.2. And it reads like you're criticising Chein et al. publication. There are many other similar publications that the analysis doesn't include. Why is the focus on Chein et al.?
