In the paper we presented the numerical results related to the unsteady effects produced by the oscillating foil in fluids. The paper was inspired by the studies over insects and birds fly. It was shown that by choosing of the frequency and amplitude of oscillations it can be generated the different kind of the vortex Karman street and this way control the drag, lift and thrust force exerted on the object. For numerical study vortex-in-cell method was used. We establish numerically relationship between Strouhal number amplitude of oscillations and vortices topology behind the oscillating foil by constructing the phase space diagram. The computational result are in consistent with the existent experimental data.
