摘　　要：以种公猪舍为研究对象,在纵向通风条件下,运用CFX软件分别对猪栏高1.2 m和0.8 m这两种情况下猪舍内气流场进行三维稳态模拟。结果显示,0.8 m猪栏时可在舍内得到非常均匀的气流场;当猪栏高度为1.2 m时,舍内的气流场比较均匀,但由于猪栏较高,猪栏对气流仍然起到的一定的限制作用,在部分猪栏内仍有气流速度过高或过低的现象。Numerical simulation of three-dimensional steady state of airflow pattern in piggery was carried out at the height of bar being 1.2m and 0.8m with CFX software under vertical ventilation,respectively.The results indicated that the airflow velocity distribution was quite uniform and uniform at the bar height being 0.8m and 1.2m,respectively.Due to the higher bar which restricted the airflow,too high or too low airflow velocity in some sweineries was observed.
