The three-dimensional flow field around a hypersonic vehicle was numerically simulated in the study. The manuscript focused on the realistic reentry plasma sheath, the electron density and temperature at the hypersonic reentry stage. It was shown that the maximal total pressure on the leeward side decreased with the angle of attack and that on the windward side increased with the angle of attack, in agreement with previous studies. The results showed that the thickness of the plasma sheath increased on the leeward side, but the electron density decreased. Since electron density is related to reduction of electromagnetic wave, so radio communication on the leeward side at a large angle of attack might overcome the communication ‘blackout’. These results might be helpful for seeking the way to eliminate ‘blackout’ at reentry stage. however, there are some flaws in the paper. The necessity of 3D simulations was not discussed. It seems that all conclusions obtained from 3D and experiments can also be drawn from 2D simulations. The three-dimensionality of the flow should play a role in determining the flow around the vehicle, which should be discussed to prove the importance of 3D simulations. Unfortunately, there is no further talk about 3D simulations, except for validating the 3D computations. One of the highlights of the study is the decreased electron density with increasing the angle of attack. The underlying physics of this event should be discussed or supposed in the paper, even though it might be still elusive. Moreover, whether this phenomenon has been found in previous 2D simulations is neither introduced nor discussed. These issues should be explored and addressed in this paper. Substantial revision following the academic standards in proper written English is necessary. For example, ‘AOA’ should be explained at the first appearance of the term. The manuscript is not recommended to publish. 發(fā)自小木蟲IOS客戶端 |

以上是審稿意見，1.主要問題審稿人要的就是三維對(duì)比二維的優(yōu)點(diǎn)在哪，為什么要用三維算流場。但是二維就算不了攻角的情況，旋轉(zhuǎn)軸對(duì)稱每個(gè)位置的流場分布都是不一樣的。我只是截取XOY比較容易分析而已，審稿專家就抓著二維也可以仿真攻角。2.確定對(duì)給出的結(jié)論分析不夠，但感覺可以進(jìn)行補(bǔ)充。3還有就是語言問題。但是最主要的問題覺得他提出來是錯(cuò)的。 發(fā)自小木蟲IOS客戶端 |
