A large-eddy simulation-based study has been carried out focusing on the coaxial and non-coaxial collisions between a R e Γ 0 = 3000 vortex ring and stationary spheres. The effect of sphere size on vortex dynamics was investigated by varying the sphere-to-vortex ring diameter ratio, D / d , from 1 t...
