The Wind Engineering, Energy and Environment (WindEEE) Dome is the world’s first hexagonal wind tunnel. Its large scale structure (25 meters diameter for the inner dome and 40 meters diameter for the outer return dome) and 106 independently controlled fans will allow for wind simulations over extended areas and complex terrain. WindEEE uniquely allow for the manipulation of inflow and boundary conditions to reproduce, at large scales, the dynamics of real wind systems including tornado, downburst and hurricane.
