Vortex breakdown phenomena in rotating fluids
- Vortex breakdown phenomena in rotating fluids are investigated both theoretically and experimentally. The fluid is contained in a cone between two spherical surfaces. The primary swirling motion is induced ba the rotating lower boundary. The upper surface can be fixed with non-slip condition or can be a stress-free surface. Depending on these boundary conditions and on the Reynolds number, novelVortex breakdown phenomena in rotating fluids are investigated both theoretically and experimentally. The fluid is contained in a cone between two spherical surfaces. The primary swirling motion is induced ba the rotating lower boundary. The upper surface can be fixed with non-slip condition or can be a stress-free surface. Depending on these boundary conditions and on the Reynolds number, novel structures of recirculation zones are realized. The axisymmetric flow patterns are simulated numerically by a finite difference method. Experiments are done to visualize the topological structure of the flow pattern and to observe the existence ranges of the different recirculating flows. The comparison between theory and experiment shows good agreement with respect to the topological structure of the flow.…
