Abstract

This paper presents a numerical (CFD) analysis of wind flow above a barrel vaulted building placed within two different urban setting (urban canyon and a staggered configuration). The building height is changed to identify the effect of the building height and the surrounding urban configuration on the wind velocity above the barrel-vaulted roof. Results show that with the increase in building height the wind velocity increases and accordingly the energy yield of a roof mounted wind turbine increases. When the building is higher than its surroundings, the urban canyon introduces more acceleration above the investigated roof than the staggered configuration. However, when the building is lower than or the same height as the surrounding urban configuration, the staggered urban configuration introduces more acceleration above the investigated roof than the urban canyon configuration.
