Effect of Wind Direction with Surrounding Environment on Shuttlecock Wind Drift and Ventilation in the Multipurpose Indoor Stadium
摘要
Shuttlecock easily deviates from the actual path due to indoor stadium ventilation known as wind drift, which leads to enormous setbacks for elite players in the tournament. To understand the impact of environment and wind direction on wind drift and cross-ventilation, Computational Fluid Dynamics (CFD) analysis is performed in the urban environment. Tamil Nadu Physical Education and Sports University (TNPESU) Multipurpose stadium and campus are subjected to the CFD study and validated with field measurement data. The study is carried out for six wind resource configurations based on the wind rose and campus surrounding terrain. The velocity contour and area-average velocity are studied for the wind drift at the plane height of 1.5 m from the ground. The major stadium area has less wind drift, area-average velocity is between 0.7 and 1.7 m/s. The air change rate per hour (ACH) is measured to quantify the stadium ventilation, ranging from 1.6 to 2.6 h−1, which is lower than the recommended rate. The ventilation is insufficient even though the TNPESU stadium is facilitated with lower wind drift.
