CFD研究表明,“平胸即正义”根本站不住脚!

注意:本文于一年前首先发布于哔哩哔哩 ,部分内容可能缺少时效性。

最近看毕导发布的关于论文投稿的视频 ,发现其中有这样两篇论文:

我对右图的研究产生了浓厚的兴趣,立即从ResearchGate上找到了这篇文章,题目是《Analysis and Qualitative Effects of Large Breasts on Aerodynamic Performance and Wake of a “Miss Kobayashi’s Dragon Maid” Character》:

看到这里,熟悉二次元的读者大概就明白啦!Miss Kobayashi’s Dragon Maid就是日本动漫《小林家的龙女仆》。研究者将该动漫中的人物Lucoa作为模型,使用日本埼玉县越谷市的气象数据进行了计算机流体动力学模拟,发现人体较大的胸部有助于减少阻力。具体研究细节我也就不班门弄斧啦,请自行移步文末出处阅读。

论文也提出了研究存在的不足,例如未曾考虑头发对于气流的影响(这可能就是论文仅在ResearchGate上公开而未发表的原因,之一)。

附论文摘要:

A computational fluid dynamics methodology is used to study the salient flow features around the breasts of a human figure and to describe the aerodynamic differences imparted by their geometric presence. Two models are proposed for examination: a 3-dimensional reference based on a character design with a significantly buxom figure and a modification of this design where the breast size is reduced significantly. The two models are tested at speeds ranging from 1 to 30 m⋅s^-1 using Reynolds-averaged Navier Stokes (RANS). Drag, lift, and skin friction forces, along with turbulence kinetic energy (TKE), are investigated and compared between the different models. The present results are expected to provide useful information on the validity of the statement, “Flat is Justice(平胸即正义)” in terms of an aerodynamic standpoint. In addition to this, the results can offer worthwhile data investigating the anthropometrical presence of large breasts on sport aerodynamics.
