• Discrete vortex methods have been often used to describe unsteady incompressible flows at high Reynolds numbers. Almost studies already existed are concerned with large scale structures of the flows interested and integrated properties, that is, lift and drag coefficients of bodies. In order to examine potential abilities of the vortex methods in describing more detailed information, a correlation function in a wake of a circular cylinder is measured by a discrete vortex method and also an experiment of an actual flow. Comparisons between them show that turbulent structures also could be well described by the discrete vortex method.
