Boundary Shape Inversion of Two-Dimensional Steady-State Heat Transfer System Based on Finite Volume Method and Decentralized Fuzzy Adaptive PID Control
Round 1
Reviewer 1 Report
A high interest method is proposed to determine the IGP by means of the use of fuzzy techniques.
State of the art is well determined and a clear structure of the procedure is given.
Nevertheless real experiments are missing and only simulation results are shown. Conclusion based in experimental results will improve the quality of the manuscript.
English should be reviewed carefully. Some paragraphs are not clear mainly due to some errors using lenguage.

Reviewer 2 Report
Authors reported the development of a shape identification scheme to determine the geometric shape of the inaccessible parts of 2D objects. This is an interesting work and seems useful for some industrial applications. However, this work is kind of a follow-up work of the previous publications from same authors. I would like to know the relations and difference among them. Overall, I would recommend publication of this work after addressing the comments. 1) In Introduction, authors should explain the relation of this work with previous ones, especially ref 2. 2) Can authors point out any potential application of this work?Author Response

Response 1: In Introduction, add: The decentralized fuzzy inference is successfully applied to invert the thermal conductivity by Wang et al. [2], and the accuracy and stability of the algorithm are verified.
Wang Shoubin and Yang Liangliang are Sun Xiaogang’s student, and both are members of sun Xiaogang's team, study different branches of inverse heat transfer problem (inversion of thermal conductivity, inversion of heat flux density,inversion of the boundary shape). [2] applied DFI to study invert the thermal conductivity. This manuscript applied decentralized fuzzy adaptive PID control algorithm study IGPs, one extended research.
Point 2: Can authors point out any potential application of this work?
Response 2: Identification of the corrosion of the inner wall of large-scale fluid pipeline and heating furnace; Identification of erosion of inner wall and hearth of metallurgical blast furnace.
