AbstractCTS-0093792Z. J. Wang, Cornell UniversityThe proposed research is a computational study of insect flight, a problem which has been studied mostly by experimental means heretofore. Unlike aerodynamics of conventional wings, the present problem deals with flow over flexible wings at low Reynolds numbers. It is always unsteady, involves simultaneous generation of lift and thrust by the wing, and strong interactions between the large vortices shed from the leading edge and the rest of the wing. The PI proposes to carry out the simulation by using the Submerged Boundary Method and vortex dynamics models. Successful methods developed for biomimetics will be useful for simulating aerodynamics of micro air vehicles.

abstractcts - 0093792 z。本文提出的研究是昆虫飞行的计算研究，这是一个迄今为止主要通过实验手段研究的问题。与传统机翼的空气动力学不同，本问题处理的是低雷诺数下柔性机翼的流动问题。它总是不稳定的，涉及机翼同时产生升力和推力，以及前缘和机翼其余部分脱落的大涡流之间的强烈相互作用。PI建议采用淹没边界法和涡旋动力学模型进行模拟。成功的仿生学方法将有助于微型飞行器的空气动力学模拟。
