Simulation Research on Piggery′s Airflow Field Under Different Window Layout
Abstract: For the animal building of natural ventilation ,the window layout has a significant impact on the indoor air flow conditions ,temperature ,humidity ,concentration of harmful gases .This article has estab-lished flat roof ,single slope ,double slope style ,bell tower roof and half bell tower roof piggery in five dif-ferent window layouts ,and simulate airflow field inside the different types of piggery under different win-dow layout using Fluent software .The results show that ,to the same piggery with same window layout , the greater the windowing ratio the more natural ventilation is got ;to the same piggery with same windo-wing ratio ,increasing the number of window ,especially the inlet window ,could help regulate the airflow inside the piggrey to form a good airflow ;and to the piggery with same windowing ratio and window lay-out ,the types of flat roof and half bell tower roof have better performance in ventilation than others .
