Final Design ?
37
State-of-the-art climatic wind-tunnelResearch project at the Technical University of Denmark and Force Technology
Sponsored by Femern Belt Link
38
state-of-the-art climatic wind-tunnel 20m x 8m closed-circuit
25 m/sec mean wind velocity (min) with turbulence grid and flaps at -5 deg C
40 m/sec mean velocity (min) without cooling elements
Water spray capabilities (simulated rain) for rain and ice
2mx2m section minimum to allow for a maximum of 10% blockage on
a 200mm wide cable or bridge section
Consistency of flow characteristics for both smooth and turbulent flow
Full turbulence spectrum (within reason) achieved through turbulence generators
Approx. 1 MW tunnel power consumption
