Research on Optimization of Parametric Propeller Based on Anti-Icing Performance and Simulation of Cutting State of Ice Propeller

Round 1

Reviewer 1 Report

-The author had explained well for the paper.

-Suggestions, can be developed for the design and can be added for the mesh convergence study, for measuring the CFD method of the simulation to the propeller test. Then, the paper will have the originality of research.

Reviewer 2 Report

The article addresses the problem of the hydrodynamic performance of the propeller under the condition of satisfying the ice strength of the propeller. Based on CFD method, the propeller pitch, thickness, and arch at each radial direction are taken as the optimization design variables, the thrust coefficient and open water efficiency are selected as the objective function, and the optimization algorithm of SOBOL and NSGA-Ⅱ is adopted.

Some clarifications are needed and some recommendations for improvements are given below.

Authors are referencing the IACS indirectly referring to lit [10] instead of the source.

Abbreviations should be addressed when used for the first time, like IOT

Line 50, sentence: “The results obtained It agrees very well with 50 the test results.”, “agree” instead “It agrees”.

Line 134, small letter in “All”

Line 183, small letter in “Credible”, or this is intentional?

Line 199, small letter in “Coefficients”

Line 200, large letter for sobol

Line 217, Compared.!

Line 309, Parte => Pareto

Line 369, “mises stress”!

The authors showed a lot of very colorful figures that follow the optimization process and suggested a flowchart. What is missing, the final characteristics of the optimized propeller(s), which one is chosen, and how it satisfies the IACS rules.

We know nothing about the ship for which the propeller has been optimized, the main particulars, and the required power for propelling the ship. The authors claim that the hydrodynamic performance optimization design method of the ice-class propeller established in this study is effective and reliable, but the propeller area/dimensions depend on the required power so it is unclear, so far, how this optimization process helps to choose the right propeller for the ice breaker or the ship that has the ability for ice breaking.
