All solid objects traveling through a fluid acquire a boundary layer of fluid around them where viscous forces occur in the layer of fluid close to the solid surface. The origins of the flow separation from a surface are associated with the pressure gradients impressed on the boundary layer. On the other han flow past a blunt body, such as a circular cylinder, usually experiences boundary layer separation and very strong flow oscillations in the . We now discuss the phenomenon of boundary layer separation, in which the boundary. Figure 11: Pressure field and separation point for flow past a cylinder.
When a fluid flows over a stationary surface, e. Analyses made on the basis of inviscid flow over streamlined. Figure 10: Flow past a circular cylinder: (a) laminar separation; (b) turbulent separation; (c). The phenomenon is termed as separation of boundary layer.
Flow separation and formation of wake behind a circular cylinder.
