Abstract
Generating large-scale 3-D air turbulences similar to real situations in spatial characteristics defies the conventional wind tunnel test procedure but is requisite for evaluating the effect of turbulence of natural wind in engineering bridges and other large structures of optimum design matching the level of aerodynamic stability required.
The authors added functional refinement to the 2-D blade rows and damper in the wind tunnel flow active system and also devised adjustable floor spires and blocks as another active flow control alternative. The prospect is good that selective use of these active flow control methods can successfully reproduce the large-scale 3-D air turbulences.
