摘要：The shape of a poultry building and the distribution of its elements (roof, windows distribution, andwindow opening) influence the velocity and temperature distribution inside the building and therefore thethermal comfort of the broilers. Considering these components, Computational Fluid Dynamics (CFD)was used to analyze the environmental conditions of 3 poultry buildings: tunnel (T), semi-tunnel (ST)and improved semi-tunnel (IST). These three buildings had the same dimensions but differed in therelative position of fans and windows. This study modelled the effect of different configurations of roof(flat or gable roof) and window design (with or without flap plate) on the distribution of temperature, airvelocity and Index of Temperature and Velocity (ITV) at animal level (0.20 m above the ground).Simulations were conducted for summer and winter conditions. In summer conditions, configuration ISTwith gable roof without flap plate had lowest air velocity 0.72±0.27 m/s and average temperature(22.9±0.9ºC) whereas tunnel configuration with gable roof and flap plate had lowest ITV (22.94±1.30ºCon average). In winter conditions, IST configuration with flat roof had lowest average air velocity (0.24m/s), whereas the highest temperature corresponded to semi-tunnel with gable roof without flap plate ofthe slot opening (19.35±2.67ºC). Finally, the lowest ITV corresponded to tunnel without flap plate andgable roof configuration (19.14±3.57ºC). According to the CFD simulations, in three configurations thevariables analyzed were within the comfort ranges reported for animals inside buildings
