Abstract:

The results of this research provide further evidence that the secondary vortexsaddle point region is critical to the formation of vortex asymmetry in conical Navier-Stokes equation set simulations. In addition, the proper technique for tracking the perturbations is explained. Sample perturbation contour plots are provided. The work continues under support from the University of Cincinnati, exploring perturbation growth rate and propagation.
