Abstract: The roof shape and orientation are crucial factors in the design of stadia for very hot climates, to regulate the wind and solar access to the bowl and ensure usability. Computational Fluid Dynamics (CFD) has been used to model the airflow in and around stadia and interface with other modelling tools to predict thermal comfort. However, relatively few experimental studies provide validation data to support simulations of geometrically complex structures. This paper presents a CFD and experimental study of a stadium with double saddle-shaped open roof. CFD results are compared with measurements carried out with Particle Image Velocimetry. The performance of the concave and convex roof profiles are discussed.
