AN EXPERIMENTAL STUDY ON AIR FLOW AROUND THE BUILDINGS (I) : Wind Tunnel Tests on Turbulent Air Flow around the Buildings, Part I

air pollution concentration around tall buildings

the concentration of pollutants around tall buildings can be influenced by many factors such as down wind effects, waves, airflow due to free convection of heat transfer, building height etc. the main objective of this research was the investigation of the variation of pollutants concentration at different heights around tall buildings. research was carried out measuring parameters such as co o...

Experimental Study on Flow Characteristics Around Twin Wind Blades (RESEARCH NOTE)

In the current study, twin wind blades are designed, fabricated and the effect of various gap ratio (g*) at various angle of attacks (α) on a next to each other twin wind blades are examined in an open-channel wind tunnel. Aerodynamic forces and moments are determined by using three-constraint force balancer. For gap ratio of zero, the aerodynamic attributes are like those of a solitary wind bl...

Laminar and Turbulent Aeroheating Predictions around Multi -Cone Configurations in Hypersonic Equilibrium - Air Flow

Modelling air flows around buildings in urban environment

In urban areas, main air flows from prevailing winds are strongly modified, depending on constructions’ morphology and urban microclimate’s effects. The meteorological data on the wind speed are often available from outside city centres whereas this wind speed is tough to assess in the urban canopy layer. The meteorological models which are developed from regional level to urban canopy layer le...

Wind Tunnel Investigation of the Turbulent Flow around the Panorama Giustinelli Building for VAWT Application

A boundary layer wind tunnel facility has been adopted in order to conduct experimental measurements of the flow field around a model of the Panorama Giustinelli Building, Trieste (Italy). Information on the main flow structures has been obtained by means of flow visualization techniques and has been compared to the numerical predictions of the vortical structures spread on top of the roof, in ...
