Did you know?
WebSometimes the swirling flow is turbulent and so energy- laden that any aircraft entering into this region of flow will face the possibility of being upset. This is called wake turbulence, and thus if the vortex strength is large enough to cause the ‘upset’ of a following aircraft, the separation between it and any following aircraft as they approach a runway has to be … WebAbstract. We present feature-extraction techniques for numerical and experimental data of complex fluid flows. Focus is placed on efficient analysis and visualization of coherent structures of snapshots, temporal evolution and parameter-dependency of coherent structures. One key enabler are Galilean invariant flow quantities based on pressure ...

Many fluid machinery applications involve swirling flow. Devices in which swirl phenomena have a strong influence include combustion chambers, turbomachines and their associated ducting, and cyclone separators. In this chapter, we examine five aspects of swirling flows: (i) an introductory description of pressure and velocity ...

Finally, the 3D vortex tubes are tracked in time using the same tracking procedure, for finding the correspondingtubes in successive time steps. The result is a description of the evolution of the 3D vortices.
