Simulation of unsteady flow past tapered circular cylinders using an immersed boundary method

Three-dimensional numerical calculations of laminar vortex shedding behind a linearly tapered circular cylinder with taper ratio 75:1 have been carried out at a Reynolds number 131 (based on the large diameter and the uniform inflow velocity) using a Finite Volume code. Computations were performed on a staggered-Cartesian grid and a direct...
