Improvement of Natural Ventilation of Post-Earthquake Transition Settlements in Dujiangyan, Sichuan

Abstract:

In the summer of 2010, we performed some on-site measurements to investigate the outdoor air temperature and wind velocity of Happy Homeland, a typical post-earthquake transition settlement of Sichuan. With the results of the measurements we found some problems in the existing planning and design of the settlements and proposed improvement which can make the transition settlements have larger volume fraction and better ventilation environment. The CFD simulation results show that the improvement can enhance the outdoor wind velocity by 19.4% and 16.7% respectively, and can raise the air changes per hour by 44.4% and 63.7% respectively, compared with the present condition.
