Computer simulations of the laminar flow past three-dimensional bluff bodies are presented. The focus is on the time-dependent wake flow behind linearly tapered circular cylinders and downstream of a circular cylinder with an abrupt change in diameter. In both cases the intricate vortex shedding phenomena observed in earlier laboratory experiments are convincingly reproduced by the computer experiments. The simulations moreover provide important supplementary information not readily accessible in the laboratory.
