• The flow of interactive vortex shedding behind a pair of flat plates arranged side by side to the approaching flow is numerically examined using the discrete vortex method. The calculated results for the plate arrangements of S/B=2.06, 1.1 and 0.5, where S is the space between two plates and B is the plate width, are compared with those of flow measurements in a wind tunnel and a water tank. The following characteristics are known. For S/B=2.06, the in-phase vortex shedding from the outer edges of both plates is more stable than the out-of-phase vortex shedding. For S/B=1.1, the flow through the space between two plates is biased and it switches quickly from one side to the other. For S/B=0.5, the switching of the biased flow does not appear.
