Simulations of Helical Vortex Instability
Abstract eng: Using dedicated DNS codes, we simulate the linear growth of perturbations in the vicinity of helically symmetric vortex systems, and extract the dominant instability properties: long-wave displacement modes and short-wave modes emerging through elliptical instability. Nonlinear simulations also reveal the complex dynamics of interacting helical vortices: overtaking, leapfrogging, merging.
