一个数学模型,调用的库塔条件占涡脱落从后缘的自由水翼在一个平面的理想流体进行比较与一个典型的模型的动力学的陆地车辆受到不可积的速度约束。库塔条件被证明是不可积的在某种意义上说,平行的约束在陆地车辆是不可积的。两个系统的动力学模拟加强了两者之间的相似性。
A mathematical model that invokes the Kutta condition to account for vortex shedding from the trailing edge of a free hydrofoil in a planar ideal fluid is compared with a canonical model for the dynamics of a terrestrial vehicle subject to a nonintegrable velocity constraint. The Kutta condition is shown to be nonintegrable in a sense that parallels that in which the constraint on the terrestrial vehicle is nonintegrable. Simulations of the two system’s dynamics reinforce the analogy between the two.
