Secondary Saddle Points and Vortex Asymmetry in Three Dimensional Flows
Abstract
In this research perturbations are placed at a variety of spatial locations and their progression in time is tracked together with side force values to link the disturbance of particular regions to the growth of asymmetry. The results of this research provide further evidence that the primary vortex/saddle point region is critical to the formation of vortex asymmetry in conical Navier-Stokes equation set simulation. In addition, the proper technique for tracking the perturbations is explained. Sample perturbation contour plots are provided. The results shown in this report are not complete, but this report gives a gist of what has been achieved as of now. The work continues under support from the University of Cincinnati, exploring perturbation growth rate and propagation in three dimensional flows.
