Study on the Influence Mechanism of Energy Consumption of Sugarcane Harvester Extractor by Fluid Simulation and Experiment
Round 1
Reviewer 1 Report
The simulation process is incomplete.
a. What is the grid size?
b. The grid study must be done.
c. What was the boundary and initial conditions?
d. Please add the other settings in the ANSYS-Fluent software. Such as under-relaxation factors…
e. In the extractor, there are two materials: the air and the sugar cane. It seems the simulation process is multiphase. Please clarify this problem. Also, how did you model this problem. It seems you must use dynamic mesh for simulation process. Please clarify.
f. If you use the SST k-w for modelling the turbulence phenomenon, the other turbulence model such as k-e is redundant. Please delete them.
g. Please add the dimensions of the model.
h. What was the version of the ANSYS software?

Manuscript “Study on the influence mechanism of energy consumption of sugarcane harvester extractor by fluid simulation and experiment”
This manuscript will be interesting for scientists, who are interested in improving the design of sugarcane harvester extractor. In order to improve the manuscript, I suggest the following corrections:
1. The manuscript states: “However, the current sugarcane production in China still cannot supply the national market [1-3]” (p. 1). There is no confirmation of this information in articles [1-3], these references are incorrect. The same applies to the reference to Book [4] in the text of the manuscript.
2. The manuscript states: “The energy consumption of the extractor accounts for about 20% of the total energy consumption of the sugarcane harvester, however, the impurity removal performance reaches 8% of the impurity rate [8-10]” (p. 1). Unfortunately, I am obliged to say that articles [8,9] do not confirm this information.
3. What does article [11] have to do with the topic of the manuscript? The Introduction section of the manuscript needs serious revision, as some of the references are incorrect.
4. Impeller rotation angular speed ω/w should be marked the same in Fig. 1 and in the text of the manuscript.
5. Relative combined velocity W/Ω should be marked the same in Fig. 1 and in the Equation (7)-(13), (17). I think the link should be to the article:
Liu, J., Tian, R., & Nie, J. (2021). Effect of impeller solidity on the generating performance for solar power generation. Journal of Electronic Science and Technology, 19(4), 100132. https://doi.org/10.1016/j.jnlest.2021.100132
Because in this article, a theoretical analysis of turbine blade forces and speeds was carried out, from which equation (7) and others were used.
6. The unit of density of micro-segment ?? should be kg/m3, not m3/kg (p. 4).
7. In Fig. 5-6, the unit of rotational speed should be specified.
8. It is advisable to indicate the direction of rotation of the blades in Figs. 5,7,9,10.
9. In the Materials and Methods section of the manuscript, it is necessary to provide more complete information about the sugarcane (shape, size, moisture content), as well as indicate the belt conveyor performance during bench test. In addition, it is necessary to describe the technique of Three-level orthogonal table L9(34) in this section, and not in section 4.2. Bench test. It is also necessary to specify how the Impurity rate and Loss rate were determined (calculated).
10. The keywords “orthogonal test” and “optimization” are general terms, so they need to be replaced.
