UrduIn Physics of Fluids, researchers explore the lift production mechanism of flying snakes, which undulate side-to-side as they move from the tops of trees to the ground to escape predators or to move around quickly and efficiently. The investigators developed a computational model derived from data obtained through high-speed video of the snakes and considered several features, such as the angle of attack that the snake forms with the oncoming airflow and the frequency of its undulations, to determine which were important in producing glide.
