An Investigation of the Quantitative Correlation between Urban Spatial Morphology Indicators and Block Wind Environment

The research purpose of this work is guiding the spatial morphological design blocks via relevant indicators to realize suitable wind environments. In doing so, it necessary find most indicator types and value ranges for each urban morphology. At present, has been based on numerical simulation ideal block shapes rarely proposes results actual types, which often tend be complex Therefore, paper firstly presents a theoretical speculation main factors influencing effectiveness analyzing physical significance formulating principles indicator. These speculations are verified environment measurement statistical analysis, indicating that porosity (P0) can used as an important guide environments in case deep street canyons, while frontal area density (?F) supplement shallow canyons with no height differences. Finally, computational fluid dynamics (CFD) quantify impact difference canyon depth ?F P0, thereby finding form P0. This provides feasible index system designers.
