Large Eddy Simulations (LES) involving the head-on impingement of vortex rings upon round cylinders were carried out in ANSYS Fluent. Two cylinder-to-vortex-ring diameter ratios D/ d=0.5 and D/ d=0.25 were examined at Re=2000 for the purpose of studying ring-boundary collision interactions and compa...
