<p dir="auto">直接和金钱相挂钩啊！飞机公司确实需要好好算计算计。哈哈。:cheeky:</p>

<p dir="auto">现在很多计算的阻力预测已经能够达到千分之一，但是大家还在致力于将其算侧更准，</p>
</blockquote>
<p dir="auto">看起来目前的湍流模型已经可以很好的预测阻力了。莫非飞机设计师还再pushCFD工程师玩点更狠的？</p>

<p dir="auto">阻力分为压差和摩擦阻力。<br />
对于blunt-body来说，算准压力分布就能很好的得到阻力系数了。<br />
而对于slender-body来说，想算准摩擦阻力很难，边界层内的现象太复杂。</p>
