ABSTRACT

The natural smoke removal is a common way of protection of the escape routes in Poland. The operation of such systems is based on the phenomenon of buoyancy. The intensity of this effect depends on the temperature difference between smoke and ambient air. The second factor influencing the natural smoke flow inside a building is wind. The wind influence is significantly important for buildings equipped with smoke removal windows. However, also the other natural smoke removal systems could be affected by the wind impact under adverse ambient conditions. There are the features of the wind described in the first section of the paper. Next, the impact of the wind on a building is shown. Two wind speeds and two wind directions were considered. A building model in the extended computational domain was built. The model was solved with the use of Ansys Fluent. The distributions of dynamic pressure caused by the wind on different facades of the building were presented. The particular attention was paid to the dependence of pressure distribution on the wind direction.
