title = "Deterministic flow field and flow structure model of asymmetric vortices over slender body",
abstract = "In this paper an experimental study of the asymmetric vortices flow over a slender body at high angles of attack has been carried out in the subcritical Reynolds number range. The deterministic nature of asymmetric vortices flow at regular state was proved in two different wind tunnels with two machined slender body models. The uncertainty of asymmetric vortices flow is triggered off by randomness of disturbance from model machining micro-irregularities but not by flow itself. On the basis of deterministic nature of asymmetric vortices flow, the flow patterns and flow structures of asymmetric multi-vortices are studied in detail. The asymmetric multi-vortices flow structure can be zoned: inception region and fully developed region of asymmetric twin vortices, asymmetric triple vortices region, four and five asymmetric vortices regions and Karman vortex street like region. The correlation between the flow structure of asymmetric multi-vortices and the behaviors of sectional side force distribution along the body axis is revealed. Finally a physical model of asymmetric multi-vortices structure at regular state was proposed.",
