Numerical Simulation of Natural Ventilation in Typical Residential Layout

In order to research the influence of layout on natural ventilation，the indoor natural ventilation environment of the typical residential layout in Lishui city was simulated by using CFD method, and the influences of building openings and the wind angle were analyzed . The paper put forwards several proposals to enhance the effect of natural ventilation based on the simulation and the analysis. The results show that indoor layout including the area and ratio of the opening can influence interior ventilation,and the layout in which cross-ventilation can form is good for ventilation,and wind angle has an effect upon indoor natural ventilation in the certain layout.
