Abstract: In this study, flow over a cylinder was investigated to understand the physics of fluid motion in the wake region. Eulerian velocity field attained from computational fluid dynamics model while Lagrangian information obtained from finite time Lyapunov exponent fields illustrated how a vortex formation takes place once it is detached from the cylinder.
