Simulation of wind flow around three-dimensional buildings

In this paper results from a computer simulation of wind flows around prismatic bodies using a k-ε{lunate} model of turbulence are compared with full scale and wind tunnel tests done by others. The agreement is good, both in the wake region and elsewhere, and is particularly good for flow around a cube in which the overall error level in both pressures and velocities is about 5-10%. This is comparable with the error achievable with well controlled wind tunnel tests
