Case (b) simulates the same problem in (a) with a single vortex representing the LEV. Case (c) is also simulated by single vortex model. Different from (b), the simulation starts at tf= 1.5s when the feeding vortices in (a) stop. The initial condition for (c) at t = 1.5s is obtained from (a) by setting the locations and circulations of their LEVs identical. In this way, case (c) only captures the process of vortex shedding.
