This paper describes a vortex modelling technique for the theoretical prediction of two-dimensional flow around circular cylinders. Examples are given of predicted flow fields and drag and lift forces in steady and oscillatory on flow and these are compared with results of experiments carried out in a test tank. The correlation between computer simulations and experiments is encouraging. The possible implications for the engineering practice are discussed.
