heal.abstract A numerical method has been developed for the computation of wake structure and development of horizontal axis wind turbines. The method uses the vortex particle concept which already has been used in order to compute three-dimensional unsteady inviscid flows around wings and helicopter rotors. It is a grid-free Langrangian free vortex method in which vorticity is discretized into a set of vortex carrying particles. The time evalution of each particle is being computed independently at each time step. The blades are represented as lifting surfaces and the exact geometry (including the nacelle) is taking into account. The governing equations are the vorticity transport equations and the Biot-Savart low expressed in Langrangian coordinates. The method was applied for the calculation of the wake characteristics of a HAWT whose geometry was chosen in correspondence to existing experimental results so that comparisons could be possible. The results include velocity profiles and vortex particles positions and velocities in the wake of the WT. In order to simulate the performance of the WT in a wind park arrangement the interaction between two turbines was calculated. © 1988. en
