以S1210型翼型为基础,设计了一种基于科恩达效应的捕风器,采用数值模拟的方法,在自然风速为3 m/s的情况下,对一尺寸为30 m×20 m×3.5 m的地下仓库实际通风效果进行了研究。研究结果表明:...展开更多 以S1210型翼型为基础,设计了一种基于科恩达效应的捕风器,采用数值模拟的方法,在自然风速为3 m/s的情况下,对一尺寸为30 m×20 m×3.5 m的地下仓库实际通风效果进行了研究。研究结果表明:在不同捕风器高度下,室内通风换气次数均在1次以上,且随着捕风器高度提升,风管进出口的速度值不断增大、负压值不断减小,进出口压力差最大为1.3 Pa;翼型壁面上形成的负压区最下负压值为-14 Pa,随着捕风器高度的提...

Based on the S1210 airfoil,a wind catcher based on the Coenda effect was designed,and the actual ventilation effect of an underground space with a size of 30 m×20 m×3.5 m was studied under the condition of natural wind speed of 3 m/s,and the results showed tha...MORE Based on the S1210 airfoil,a wind catcher based on the Coenda effect was designed,and the actual ventilation effect of an underground space with a size of 30 m×20 m×3.5 m was studied under the condition of natural wind speed of 3 m/s,and the results showed that the number of in...
