Abstract
We develop a Vortex Particle-Mesh (VPM) method for the Large Eddy Simulation of wind turbine wakes and coarse scale aerodynamics.
Based on the vorticity formulation of the Navier-Stokes equations, the approach combines the advantages of two discretizations. The particles handle the advection of vorticity, and exploit its compact support. The mesh is used for the evaluation of the differential operators and inside efficient Fourier-based Poisson solvers.
The blades are modeled by means of lifting lines. This treatment is similar to a vortex lattice method, although it is here immersed in the mesh and allows the evolution of shed vorticity into a fully turbulent flow.
We apply this tool to the investigation of atmospheric turbulence effects on the blade aerodynamics and on the wake behavior. To this end, the inflow boundary is feeding our VPM calculations with a turbulent vorticity field that has been computed in a preliminary LES of atmospheric turbulence.
