Optimisation of Highly Efficient Composite Blades for Retrofitting Existing Wind Turbines

Round 1

Reviewer 1 Report

The objective of this study is to increase the wind turbine rotor blade power capture efficiency and enhance its structural performance. The article is written well. However, as a reviewer, I am suggesting a few modifications for improving the overall quality of the manuscript.

1.       The digital twin which is introduced as a keyword never used in the manuscript.

2.      Suggest including the limitation of this study.

 

3.        The authors should compare their method with recent related works including 2022 papers.

Energies-2087768 Optimisation of Highly Efficient Composite Blades for Retrofitting Existing Wind Turbines

This paper focuses on the wind turbine blade power efficiency increment and structural performance enhancement using a methodology aiming to upgrade rotor blades for existing wind turbines to extend the turbine life. The topic has great potential to improve energy efficiency and power stability. Thus, this reviewer appreciates the significance and integrity of this study. Generally, before consenting to publication, the issues listed below should be addressed by the authors.

- The overall presentation of exciting numerical knowledge is fair, but it should be improved by adding more detailed references about the numerical simulation method. For instance, the author may introduce more about the microscale or mesoscale simulated method in the field of power production prediction and evaluation, such as DOI: 10.1016/j.enconman.2022.115897; DOI: org/10.1016/j.energy.2020.117913.

- The creative point of this paper needs to be further clarified in the Introduction. The authors explain the research status but the shortages of existing works are little involved, inducing that it is hard to tell the innovation and contributions of this study.

- The results were given in detail for several conditions, but there needs more discussion and analysis for the results compared with the previous relevant studies.

- The conclusions should be improved.

Reviewer 3 Report

My general evaluation for the article titled “Optimization of Highly Efficient Composite Blades for Retro fitting Existing Wind Turbines” is as follows.

  It is a study in the field of “Rotor blades for existing wind turbines”.

1. The abstract should be revised. The technique-method can be stated briefly. The purpose is not clearly stated.

2. In general, the English language of this article should be corrected. Professional help is recommended.

3. For the Introduction section, make use of recent sources. It is also recommended to replace References 2 and 25. Use other references instead. I don't see fit for the "Wikipedia" reference display.

4. For the Materials-Methods section:

a- The lettering (a-b) should be shown in Figure 8-9.

5. In the Conclusions section, the superiority and difference of the article from other existing studies should be clearly stated.

6. Make use of recent studies in the References section. Usually, old references are used.

7. IMPORTANT:  37 references were cited in the article. But there are only 29 in the References section.
