EXPERIMENTAL INVESTIGATION OF THE AIRFLOW AROUND SUPPORTED AND SURFACE MOUNTED LOW RISE RURAL BUILDINGS

Abstract

In this study, the flow around a rural building for both supported and surface mounted cases has been investigated. For this purpose experimental studies are performed. Hot wire anemometry was used to measure the stream-wise velocity in the wind tunnel. The experimental data depict that no recirculation zone exists in front of the supported building and the reattachment length behind this building decreases compared with that for the surface mounted building. Turbulent intensity was also measured and its variation around both building models is compared.
