An Optimization design Approach of Football Stadium Canopy Forms Based On Field Wind Environment Simulation

After the issue of General Plan of Chinese Football Reform in 2015, the development and construction of football stadium in China was put on an important agenda. Field wind environment will make a serious impact on players' performance and game result，while canopy form plays great effect on field wind environment. The primary intention of this research is to reveal the relationship between field wind environment and canopy forms based on CFD simulation of wind environment, then construct an optimization design approach of football stadium canopy form . STAR-CCM + 9.04.009 is set as simulation platform in this paper. As for the current developing status of football game in China, a 30,000-capacity medium-sized football stadium model is proposed for research object. And then CFD simulation is carried out on the canopy section profiles and the canopy connection permeability, different external wind speed such as 5 m/s, 10 m/s, 15m/s, flows into the model from east side in all the cases. Furthermore, the wind field distribution uniformity and wind speed variation stability are taken as the evaluation criterion. In this way,the impact mechanism which different canopy forms play on the field wind environment in football stadium is attempted to characterize from the experimental results. Finally the proposal of the football stadium optimal design strategies are put forward.
