Paulo D. F. Gouveia, Alexander Plakhov, Delfim F. M. Torres

摘要:

我们调查,通过计算机模拟,形状的非凸体,最大限度地提高他们的运动阻力,通过稀薄介质,考虑到身体向前移动,同时缓慢旋转。一个二维的几何形状,赋予身体的电阻非常接近的理论上确界值,改善以前的结果。

英文摘要:

We investigate, by means of computer simulations, shapes of nonconvex bodies that maximize resistance to their motion through a rarefied medium, considering that bodies are moving forward and at the same time slowly rotating. A two-dimensional geometric shape that confers to the body a resistance very close to the theoretical supremum value is obtained, improving previous results.
