An Aero-Optical Effect Analysis Method in Hypersonic Turbulence Based on Photon Monte Carlo Simulation

Round 1

Reviewer 1 Report

 

In this paper, an aero-optical effect analysis method based on Photon Monte Carlo Simulation (MC-AOEA) is proposed. This method considers the absorption and scattering effects of photons and explains the phase distortion and energy loss caused by aero-optical effects from the perspective of micro statistics. The work is interesting but lacks experimentation. Therefore, this manuscript is worth publishing in photonics. However, the author needs to address my concerns as follows.

1.       The English expression may be modified appropriately, and the references should be checked carefully.

2.       The format of footnotes and pictures of references in the article should be consistent with the full text.

3.       The representation in Figure 4 needs to be optimized, and the dashed line representation needs to be clearly labeled.

4.       The fonts in the article are inconsistent and the full-text format is consistent.

5.       The article only mentions that the new method needs to be verified by experiments.

Reviewer 2 Report

The effect of hypersonic turbulence on photon propagation near the platform surface is  simulated with a Monte-Carlo approach, considering scattering and absorption effects of air molecules.

[1] Line 149: Please rephrase “phase function reflecting scattering distribution”.

[2] Line 161: Please double check “value of s and s”

[3] Line 213: Please specify the range of roulette parameter ``m’’.

[4] Lines 220-224: Please rephrase the following statements: “Note that when calculating the

incidence angle, if a photon just touches an angle or edge of the grid, the incidence angle

is not defined theoretically. If the photons are very close to the corner or edge, the uncer-

tainty will be broken by selecting the first grid through which the photons will travel in a

straight line."

[5] Line 263: Please give the full name of ``SR’’.

[6] Line 287: Suggest to change “The total number of mesh generation” to “The total number of cells’’.

[7] Fig.7: Does ``optical simulation threshold’’ mean ``optical simulation boundary’’?

[8] Line 293: Please elaborate ``the deviation of average velocity’’.

[9] Fig.11(b): Please double check the vertical label.

[10] Line 378: Please rephrase ``transition degree of turbulence’’.

[11] Table 1: Please elaborate how the 11error of offset angle’’ is defined.
