Bio-Inspired Textiles for Self-Driven Oil–Water Separation—A Simulative Analysis of Fluid Transport

Round 1

Reviewer 1 Report

- I strongly recommend the addition of the list of symbols
- The desription of the numerical model is somehow messy.
     - line 150: "the NSE can be converted into finite difference" - however further the Authors claim that they use finite volume method, not finite diference one
     - Fig. 3a - it is not clear if on the wall on left side the periodic BC are fulfilled or it is the inlet
     - How are defined the boundary conditions at the surfaces of piles (no-slip bc?)
     - Does the shape of piles is given as steady and fixed - or it is a result of interaction with fluid flow? In the last case - how is the force calculated?
All these issues should be addressed.
- Line 251 "The transport is recorded..." - what EXACTLY is recorded? The velocity flow? If so - how was the velocity measured?

- line 475-480: "The parameter study shows that the oil transport velocity can be increased by (...) can be increased" - the repeated fragment. After that, the list of factors (lines 477-479) is somehow strange - I recommend to use the typical form with e.g. bullets

Reviewer 2 Report

Simulative analysis in this work has certain scientific and practical significance, but it is still far from sufficient to reflect its guidance for practical innovative products, Bio-inspired textiles. Firstly, the design parameters based on biomimetic models need to be analyzed and fully obtained. This is only mentioned in Figure 1 and its discussion. More importantly, the model design is completed without any actual corresponding biomimetic "products" (textiles) to verify it, resulting in a significant loss of credibility of the design.

Reviewer 2 Report

Good, no any more comments.

Reviewer 3 Report

The manuscript has been sufficiently improved to warrant publication in Biomimetics
