Bursting on non-rectilinear vortex loops with initial core-size perturbations

ORAL

Abstract

Vortex tubes with initial core-size variations can develop twist waves and their collision leads to a sudden expansion of the vortex core, known as vortex bursting. In our earlier work, we analyzed vortex bursting on rectilinear vortex tubes using direct numerical simulations at circulation-based Reynolds number of 5000. Here we extend that work by analyzing numerical simulations of vortex bursting on non-rectilinear vortex loops, with specific focus on the effect of the core-line geometry on the bursting mechanics and vice-versa.
