研究了浸入式湍流水射流中浮球的位置。利用射流速度分布的自相似特性，在球体静态和可变形的重标空间中建立了平衡问题。这种方法被发现与弹性重构问题有关，其中弹性产生于流动的几何形状，而不是物体的实际变形。
The position of floating spheres trapped within an immersed turbulent water jet is investigated. Using the self-similarity properties of the jet velocity profile, the equilibrium problem is formulated in a rescaled space where the sphere is static and deformable. This approach is found to be related to a problem of elastic reconfiguration where elasticity arises here from the geometry of the flow instead of an actual deformation of a body.
