冬奥会跳台滑雪项目赛道核心区气流防控装置模拟设计方法

CFD-based design method of airflow prevention device in core area of ski jumping event in Winter Olympics

跳台滑雪项目赛道核心区气流稳定性对于运动员安全至关重要。为满足跳台气候防护需求,提出了赛道核心区气流防控装置形态模拟设计方法和流程。采用CFD模拟方法,精准控制运动流线上最高侧向风速不超过5 m/s;兼顾装置美学特性,设计不规则曲线形态的气流防控装置,在保障运动员运动安全的同时,提升观众观赛体验。该方法提升了赛道剖面运动流线以下低风速区面积和整体气流稳定性,解决了跳台滑雪核心区风环境干预难的问题。

The stable airflow in the core area of the ski jumping event is of vital importance to the safety of athletes.In order to meet the climate protection needs of the ski jumping event,proposes a simulation-based design method and a process for the airflow prevention device shape in the core area of the track.Uses the CFD simulation method to accurately control the maximum lateral wind speed on the movement streamline to not exceed 5 m/s.Taking into account the aesthetic characteristics of the device,designs an irregularly curved airflow prevention device,which can ensure the safety of athletes and improve the spectator’s watching experience.The simulation analysis shows that the climate protection device proposed in this work can significantly increase the area of the low wind speed area below the track profile movement streamline,improve the overall airflow stability of the track profile,and effectively solve the problem of difficult wind environment intervention in the core area of ski jumping.
