We present a novel method for the simulation of the aerodynamic admittance in bluff body aerodynamics. The method introduces a model for describing oncoming turbulence in two-dimensional discrete vortex method simulations by seeding the upstream ﬂow with vortex particles. The turbulence is generated prior to the simulations and is based on analytic spectral densities of the atmospheric turbulence and a coherence function deﬁning the spatial correlation of the ﬂow. The method is validated by simulating the turbulent ﬂow past a ﬂat plate and past the Great Belt East bridge. The results are generally found in good agreement with the potential ﬂow solution due to Liepmann.
