Flying snake wake visualizations
We are using the immersed boundary method to study the aerodynamics of flying snakes, in a collaboration with Jake Socha and Pavlos Vlachos at Virginia Tech.
We submitted the first paper on the aerodynamics of flying snakes in 2013, and we have prepared some animations of the vortical wake behind the anatomically correct snake-cross section to supplement the results presented in the paper.
