In order to improve the calculation accuracy of the vortex generator（VG）parametric model, the parametric model application method was studied. Firstly, the method for the adding position of source term in the calculation domain and value of vortex core radius were proposed. Then, based on DU91-W2-250 blade segment, the maximum vorticity circulation algorithm considering the interaction of VG blades was used to compare the calculation results of the parametric model and the entity model under different VG spacings, VG inflow angles and airfoil angles of attack to verify the application feasibility of the above method. The results show that the parametric model and entity model are in good agreement with the experimental data, which proves that the high accuracy of the two simulation methods. In addition, under different working conditions, the velocity vectors and boundary layer velocity profiles obtained by the two models have high consistency, which proves that the parametric simulation method is effective and universal for wind turbine blades.
