First methodology activities related to Wind Tunnel testing and CFD have been carried out by CSTB and ALTRAN. Corresponding reports will be delivered soon.

Many interesting conclusions were drawn :

  • Unsteady simulations have to be considered for some operating points
  • Complementary ground vortex capture methods have been set up
  • Cutting-edge visualization means will be effectively performed during  Wind Tunnel Testing
