Abstract
The living environment of the rural livestock has the influence on livestock health and production performance. Its living environment in general is composited by the warm air temperature, humidity, airflow (wind) speed and solar radiation. Air flow conditions within the livestock and poultry establishments have a significant impact on livestock living environment and other factors. In this paper, the method of computational fluid dynamics is used to analyze the distribution of the velocity field and temperature field within the fan imports and corridor export conditions of livestock and poultry breeding places. The results show that: the airflow in the vicinity of the air inlet fan speed larger maximum reach 6.09m / s, the wind speed is low in the other regions. In Breeding places, the air flow near the fan on both sides of the wall near vortex, the more the more obvious near the center of the vortex of the place. The temperature near fans inlet is significantly lower than that near the other regions. The research results will provide ventilation of livestock breeding places designed to provide a theoretical basis and guidance.
