Abstract: The plan arrangement of residential quarters has a great effect on the outdoor pedestrian-level wind environment.In order to obtaining the velocity distribution around the buildings for the wind comfort analysis, numerical simulation Was carried out by using the Reynolds averaged equations and the RNG k-εturbuhnce model. These buildings were arranged by changing the x-direction or y-direction distance.On comparing the different plan arrangement simulation results, we can get the influence to the wind environment of the two elements stated above.
