Abstract:The across-wind effects on a special-shaped tall chimney are studied. RMS value of lift coefficient and Strouhal number are obtained by unsteady numerical simulation. Time history response of a 210m-high special-shaped chimney is analyzed, and some useful data and conclusions are obtained.

Keywords:special-shaped tall chimney; across-wind dynamic response; CFD simulation; time-history analysis
