This paper takes the traditional large house dwellings in northeast Hunan province as the research object and uses CFD technology to study the natural ventilation law of the large house dwellings. Firstly, through the field investigation of the large house dwellings in northeast Hunan province, the type analysis of the large house plane, groove door and patio is made, and the wind environment simulation research prototype is extracted. Then, CFD simulation software is used to calculate the characteristics of indoor and outdoor wind environment of traditional large house under different conditions. The results show that: 1. The indoor wind environment of slave type house is better than that of cascade type house and contiguous type house;2. The setting of the groove door is favorable to the indoor wind environment; 3. The setting of the passing hall is not conducive to the spread of indoor wind environment. This study reveals the ventilation characteristics of traditional large house in northeast Hunan province, and can provide reference for modern architectural design.
