摘　　要：针对现代化鸡场高密度饲养使鸡舍产生过量有害气体,导致鸡的产量及鸡肉品质下降问题,采用数值模拟方法,建立数学模型,分析进风口数量、位置、入射角度及风机流量变化对整个鸡舍通风状况的影响,探讨最佳通风方案,在最短时间消除舍内有害气体。结果表明,入射角越大,两个入射口间距越大,流场覆盖面越广,流动效果越好。Aimed to exceed harmful gas produced by high density raising broiler, quality and quantity of broilers were reduced. Adopting simulation method, mathematics model was established. Inlet numbers, location, inset angel and flux variation were analyzed to obtain an optimal ventilation proposal. Harmful gas was eliminated in the shortest time. In conclusion, the inlet angel and the two inlets distance are bigger, the fluid field＇s area is greater and the effect of the fluid is better.
