This research aims to understand the impact of swirl on vorticity amplification in the Navier–Stokes equations, investigating the role of geometric frustration.
Direct numerical simulations of two interlaced vortex tubes with opposite swirl in three-dimensional incompressible Navier–Stokes equations.
Analysis of vorticity growth with and without swirl under different conditions.
Comparison of results to geometric frustration mechanisms identified in vector shell models.
Maximum vorticity with swirl grows by a factor of 3.7 (from 10.3 to 38.0), while without swirl, it only amplifies by 2.0.
Swirl induces a statistically steady turbulent state without a finite-time singularity, unlike scenarios without swirl.
Geometric frustration prevents coherent forward energy transfer, acting as a barrier against blow-up in the equations.
