Effects of Wind Speed and Heat Flux on De-Icing Characteristics of Wind Turbine Blade Airfoil Surface

Round 1

Reviewer 1 Report

Comments and Suggestions for Authors

In this study, numerical simulations were used to investigate how conditions such as wind speed and heat flux affect the defrosting process. The effects on the reduction of ice thickness on the airfoil surface at different wind speeds and de-icing times under different conditions were analyzed. The results of this study provided important insights into how wind turbines can be used in real-world applications to improve aerodynamic performance and safety. Although the study is well organized, I believe that some points should be improved before publishing the manuscript.

-       Please, revise the Introduction part, emphasizing the relevance of the study to coatings.

-       Based on reference 35, temperature, water content, medium volume diameter, angle of attack values were determined. It would be good if the authors add such details under which regions these values were determined.

-       Please compare the findings with the literature.

Reviewer 2 Report

Comments and Suggestions for Authors

This paper present the effect of wind speed on wind turbine subjected to heat flux to counteract icing condition. The problem is well posed and discussed along with the background model adopted and the literature review performed. There are some changes to be applied, both to the text and to the figures presented.

 

List of corrections

·       Abstract pose the problems and provide numbers obtained without a rationale. The de icing system type should be discussed along with the selected range of wind, activation time and thermal heat power. The abstract should be more open to the description of the rationale of the research

·       Nomenclature should be before introduction

·       Line 50 Report a schematic section of the selected solution for de icing

·       Line 98 states that de icing mechanism under different wind speed have not been considered  extensively. Regarding the application proposed there is also a change in local g axis that would induce a post melting behavior of droplets and ice section to be considered.

·       Table 1 formatting can be corrected in third column description

·       Table 2 should be posed before section 2.3

·       Could authors provide a better explanation why the model is relatively accurate in the peaks but not in the plateau in Figure 5?

·       Could the authors provide a rationale behind the choice of the heating sequence? Has been applied a sort of optimization in time and power duty cycle?

·       Figure 7b, 8, 10b, 1, 13b, 14 , 16, 17, 19a, 20  have a background not conformal to standard. Is there a specific reason for that or can it be posed with white background?

·       Conclusion could encompass also further developments in the research activities.
