物体的表面形状在空气动力学中很重要。我们展示了排球的表面图案如何改变其空气动力学性能。传统的六面板排球在沿着横向和对角方向上表现出不同的空气动力学特性。有趣的是,具有六边形或凹坑的各向同性表面图案使我们能够实现各向同性空气动力学。这一结果提供了深入了解表面介导的飞行控制弹丸通过抵抗流体介质。
Surface patterns on objects are important in aerodynamics. We show how surface patterns on volleyballs modify their aerodynamic performances. Conventional volleyballs with six panels show different aerodynamic characteristics along transverse and diagonal directions. Interestingly, isotropic surface patterning with hexagons or dimples enables us to achieve isotropic aerodynamics. This result gives insight into surface-mediated flight controls of projectiles through resisting fluid media.
