强风和洪水中的叶片卷起和滑水
Leaf roll-up and aquaplaning in strong winds and floods
摘要：
柔性植物、真菌和固着动物被认为在风和水中重新配置，以减少作用在它们身上的阻力。例如，在强风中，树叶卷起成圆锥形，与具有类似形状和灵活性的剪纸相比，可以减少颤振和阻力。在山洪暴发时，草本阔叶植物在水面上形成滑水板，减少阻力。一个简单的数学模型的柔性梁沉浸在一个二维流也将重新配置流。人们不太了解的是，三维流动中二维叶子的机械特性如何被动地允许卷起和滑水。在这项研究中，我们电影叶片卷起和滑水在树和藤叶在强风和水流。
英文摘要：
Flexible plants, fungi, and sessile animals are thought to reconfigure in the wind and water to reduce the drag forces that act upon them. In strong winds, for example, leaves roll up into cone shapes that reduce flutter and drag when compared to paper cut-outs with similar shapes and flexibility. During flash floods, herbaceous broad leaves aquaplane on the surface of the water which reduces drag. Simple mathematical models of a flexible beam immersed in a two-dimensional flow will also reconfigure in flow. What is less understood is how the mechanical properties of a two-dimensional leaf in a three-dimensional flow will passively allow roll up and aquaplaning. In this study, we film leaf roll-up and aquaplaning in tree and vine leaves in both strong winds and water flows.
