A CFD Simulation of Indoor Natural Ventilation of a Residential District in Zhuzhou

With the promotion of building energy conservation, many residential areas are closely link with energy saving in design phase, and natural ventilation becomes the key to reduce building energy consumption. Thus, house design and building distribution of residential district is particularly important. Computational fluid dynamics (CFD) get rapid development in recent 20 years, especially in architectural design. This text established a model of part of a residential district in Zhuzhou based upon ANSYS FLUENT CFD software, and used numerical simulation method to simulate the condition of indoor natural ventilation under typical summer climate when the doors and windows of buildings were opened. The distribution regularities of indoor velocity field and pressure field and etc have been gotten. These data provide a theoretical basis to evaluate the building distribution of residential area.
