These animations show the vortex wake behind a snake cross-section (two-dimensional profile), obtained with full Navier-Stokes simulation. The solver is an immersed boundary method that uses GPU hardware, cuIBM (open-source under the MIT license). The cases shown vary in Reynolds number (Re=1000, 2000) and angle of attack (30, 35 and 40 degrees).

The cuIBM is fully validated with analytical solutions, published experimental data, and published numerical results. The validation report is available on figshare (follow the link below).

This video supplements results that are being prepared for publication under the tentative title "Lift and wakes in flying snakes" (Anush Krishnan, J. J. Socha, Pavlos Vlachos, L. A. Barba). This information will be updated once we submit the paper.
