An inquiry into the reliability of urban-revel cfd-based air flow field analysis

R. Cetin, A. Mahdavi

Abstract: Computational fluid dynamics (CFD) tools are widely used to address, among other things, large-scale urban climatic questions. CFD applications have the potential to provide whole-flow-field data, a detailed representation of the micro-climatic conditions within a complex urban geometry. However, the reliability of the predictions depends on wide range of variables and input assumptions. In the present study, we explore the predictive performance of a CFD tool with a statistical approach by comparing numerous site measurements and respective simulation results. This is followed by a parametric study that analyses the influence of a number of factors such as assumptions pertaining to geometry and surface properties, boundary conditions, and selection of the reference weather station.
