Simulations of the near-wake of an actuator disc and horizontal axis wind turbine
The application of a 3-dimensional Lagrangian vortex particle method has been assessed for modelling the near-wake of an axisymmetrical actuator disc and 3-bladed horizontal axis wind turbine with prescribed circulation from the MEXICO (Model EXperiments In COntrolled conditions)

In the current paper, a method for deriving the analytical expressions for the velocity and vortex stretching terms as a function of the spherical multipole expansion approximation of the vector potential is presented. These terms are essential in the context of 3D Lagrangian vor

3D Lagrangian VPM-FMM for Modelling the Near-Wake of a HAWT
The development of a stable, accurate, and efficient numerical solver for large-scale wind energy purposes
Traditionally, the design of the Horizontal Axis Wind Turbine (HAWT) has relied on momentum-based methods such as the Blade Element-Momentum (BEM) models. With the growth of computational power, optimization of wind turbines by using Computational Fluid Dynamics (CFD) for the exp
