摘要

Basing on the house layout of Happy Homeland, a typical transitional settlement with high building density after Wenchuan earthquake, the relation between the length of prefab house and air flow field was studied by using CFD. The CFD simulation result showed that when the length direction of house paralleled the summer prevailing wind direction, the longest house of 12 standard rooms would realize a best summer outdoor wind field to improve the thermal environment of settlement, and the high outdoor wind velocity would be avoided in winter as well. Additionally, although the summer indoor natural would be worst, it would be easily remedied by a household fan.
