PREDICHAT: First Order Performance Calculations of Windturbine Rotors Using theMethod of the Acceleration Potential

摘要

A method is described for the calculation of aerodynamic loads on a horizontalaxis wind turbine rotor. The method is based upon acceleration potential theory. An approximate solution of the boundary value problem has been obtained using a matched asymptotic expansion technique. Furthermore a numerical integration procedure has been applied for the integration of the pressure field gradient necessary for fulfillment of the final boundary condition. A partial delinearization of the method concerning the axial induction velocities turned out to be necessary. This is carried out in a numerical integration step.
