This repository contains the programs to simulate the evolution of a perturbed infinite vortex sheet in two dimensions. The program mainly solves the discretized Birkhoff-Rott equation. The details of the approach are provided in the documentation: https://www.flowphysics.com/vortex_sheet_evolution
This work was presented in the 2014 APS DFD conference.
The state of the vortex sheet after t = 0.98 (non-dimensional time) after perturbing with a single primary sinusoidal perturbation:
The state of the vortex sheet after t = 0.98 (non-dimensional time) after perturbing also with a secondary sinusoidal perturbation:
