Computational analysis of wind drift and ventilation comfort in a different isolated barrel roof configuration for badminton stadium

The design and construction of the badminton stadium pose a unique wind engineering challenge due to the increase in complaints related to wind drift in badminton tournaments. It is caused by heating ventilation and air conditioning or natural/cross-ventilation systems in the stadium. This paper addresses cross-ventilation efforts on barrel roofs, which are widely used for indoor stadium construction. The computational fluid dynamics analysis is carried out on the flat roof before the barrel roof to validate the wind tunnel data from the literature, and the grid independence is studied. The simulation is performed with a shear stress transport k–ω model with a three-dimensional steady Reynolds-averaged Navier–Stokes (RANS) approach. The cross ventilation for the three different barrel roof configurations with two opening directions is studied in the numerical simulation to understand the influence over volume flow rate and velocity profile near the ground (h = 20 m). From the velocity contour, it is concluded that the longitudinal direction with a height less than 5% from the standard roof (h = 100 mm) performs better than other configurations.
