The influence of the shapes of a model of an individual house on the pressures of the air currents in the wind

Abstract

Wind tunnels have been largely used when numerical methods don’t retrieve satisfying re-sults. Pressure values cannot be obtained using numerical methods in different areas of a model because they are not yielded individually. These values are important in determin-ing the forces that act on the different components of a model or structure. By using wind tunnels and by carefully placing transducers (Pitot – Prandtl tubes) in the areas that are of specific interest we can acquire the exact distribution of pressure values which can be subsequently used in determining the forces that take place around the model. In this arti-cle we are presenting the results obtained through experimental tests done in a wind tun-nel owned by the Faculty of Naval Architecture on a scaled down model of an individual house. Using a Pitot – Prandtl tube that was placed in specific areas we observed and measured the pressures that formed at different wind speeds and incidence angles.
