A New Numerically Improved Transient Technique for Measuring Thermal Properties of Anisotropic Materials
Round 1
Reviewer 1 Report
Comments and Suggestions for AuthorsThis paper introduces a novel numerically improved transient technique for measuring the thermal properties of anisotropic materials. Traditional transient methods generate a dynamic heat flux within the sample, causing the temperature to vary over time, known as the temperature response. The theoretical temperature function, which is the solution to the heat conduction equation, is then fitted to this temperature response to obtain the values of the material parameters. However, discrepancies between the theoretical model and the actual experimental setup can lead to systematic errors in determining the material parameters. Therefore, the more accurate the theoretical model, the better the estimation of the material parameters. Compared to previous methods, the improvements in this paper's technique lie in the enhancement of the analytical formula of the EDPS method through finite element simulation experiments, thereby increasing the accuracy of the results. Additionally, by replacing experimental measurements with numerical simulations of the MDPS method, the accuracy of the results is further improved. This paper will interest the researchers in thermal measurement or related domains. I can recommend acceptance of this paper after some minor issues are addressed.
1. The authors mention that the accuracy of the measurement results is improved by simulating experiments using the Finite Element Method (FEM). However, is this simulation method applicable to materials with varying thicknesses and thermal conductivities? Are there any limitations or constraints associated with this approach?
2. The authors mention that the accuracy of the measurement results is dependent on the material's thickness and thermal conductivity. For materials with high thermal conductivity, can this technique still maintain high accuracy in its measurements? If not, how will future research address this issue?
3. For some nonlinear thermal materials, saying that conductivity or density is varying with temperature, does this measurement method work as well? The authors are encouraged to give some discussion in the paper.

Reviewer 2 Report
Comments and Suggestions for AuthorsThis manuscript describes the numerically enhanced transient technique for measuring the thermal properties of anisotropic materials.
The first author uses the dynamic plane source method in most of his papers (11 references are given of his manuscript: 7, 11, 23, 26, 27, 28, 29, 30, 31, 32, 36).
The type of sensor used as well as the operating range and accuracy over temperature should be specified.
The units of measurement should be given in accordance with the SI system (e.g. kg m-3, not kg.m-3)
Measurement symbol should be written when physical quantities appear for the first time, for example: line 124 heat capacity (c)... and so on.
It must be stated what the scientific contribution of this work is.
The manuscript has no conclusion.
