Parallel Large Eddy Simulations of Wind Farms with the Actuator Line Method

Parallel Computation of wind farm Large Eddy Simulations (LES) requires the use of with Wind Turbine Models (WTM). CFD and WTM demand different domain decompositions as optimal CFD and WTM decompositions do not necessarily coincide. Nevertheless, data exchange between CFD and WTM must not penalize overall simulation performance. A coupling strategy for data exchange is described and has been tested. It enables the parallel simulation of wind farms with WTM. Simulations of wind turbine wakes have been achieved. Preliminary results show the parallelization works properly but that the simulations do not resolve flows with enough accuracy.
