Abstract

Natural ventilation is a commonly applied way in building engineering to ensure a healthy and comfortable indoor climate. In this paper CFD simulations of the natural ventilation of a large semi-enclosed stadium in the Netherlands are described. Simulations are performed to assess the air exchange rate for a total of eight wind directions. The CFD model consists of both the complex stadium geometry and the urban environment in which the stadium is located. A grid sensitivity analysis is conducted, furthermore, validation of the CFD model is performed using full-scale 3D wind velocity measurements. Comparison of the calculated air exchange rates showed that the wind direction has a significant effect on the air exchange rate; differences up to 100% were found for the air exchange rate, which can be explained by the position and size of the buildings upstream of the stadium.
