VXturb

The animation illustrates a one-to-one comparison of the 2D buffeting response generated by a semi-analytical aerodynamic model and a CFD model, both of which are subjected to synthetic free-stream turbulence.

The animation shows flutter and limit cycle oscillations of the Great Belt Bridge, subjected to sinusoidal vertical gust with identical frequency as the torsional frequency.

The animation shows sinusoidal vertical gust simulated in CFD using. The inflow particles are generated using a numerical Active Turbulence Generator.

The animation shows buffeting of the Great Belt Bridge, which has been simulated using a Turbulent Pseudo-3D Vortex Method, considering wind effects on only the deck with synthetic random free-stream turbulence. Six representative CFD planes are shown out of fifty considered along the deck.
