How does altering synchronization of pitching parallel foils change their wake dynamics?
Ahmet Gungor, Muhammad Saif Ullah Khalid, Arman Hemmati
This study was inspired from the swimming habits of red nose tetra fish that prefer side-by-side configurations and exhibit changes to their synchronization mid-swimming. Using num…
