Sphere wake
WebJun 10, 2001 · The net force on the sphere has previously been ascribed to fluctuations in the bound vorticity in the meridian plane normal to the force, produced by large-scale coherent structures shed into the wake. A simplified model of vortex shedding is proposed that involves coherent eddies in the form of a succession of randomly… View on … WebOct 19, 2024 · The wake characteristics of the sphere cavitating flow were further analyzed using a spectral analysis of the wake. The results for σ = 0.75 for Mesh 1 were chosen as an example to further study the complex cavitating flow structures in this section and the cavitation–vortex interactions in the next section.
