    Abstract

    The random vortex method is applied to flow around multiple circular cylinders using the vortex-in-cell method with overlapping meshes. The overall scheme is a combination of various aspects which have developed previously. We limit ourselves to the laminar condition in view of the absence of a reliable general turbulence model for unsteady flow and because many large-scale wake phenomena are similar across a very wide range of Reynolds numbers. Computations for two cylinders in side-by-side and tandem arrangements at a Reynolds number of 200 reproduce most of the range of flow phenomena observed experimentally. While clearly not predicting full-scale flows directly this computational capability could be of value in analysing flow and force characteristics for general multiple cylinder arrangements.
