DEVELOPING COMPUTATIONAL FLUID DYNAMICS CONDITIONS FOR URBAN NATURAL VENTILAITON STUDY
Computational fluid dynamics (CFD) is a promising method to study the urban built environment. However, the pecularities of the urban wind environment are difficult to simulate with a CFD package. The aim of this work is to develop CFD model capable of simulating the urban boundary layer which can then be used to investigate the effects of built form on the pressure coefficient regeme. The model concentrates on two aspcepts: the boundary conditions and domain size. The main methodologies involve developing a CFD boundary lasyer model and testing it against the results of physical modelling in a biundary layer wind tunne. The domain size is dependent on the building area, density and layout. The results of this work are an acceptable cFD model which can then be used to investigate specific problems.
