摘要
本文用三维紊流正交数值模似，定量分析了各种因素对控制风速的影响，得到了最佳几何尺寸的计算公式和相应的ｖ＿ｘ计算图表。初步应用表明，达到同样的通风效果，若采用优化几何尺寸，系统风量平均可减少１３％，节电达３０％左右。
The authors of this paper using the numerical simulation with a 3Dturbulent model, calculate the effects of different factors on the control velocity ofthe local air-exhaust hoods and develop formulas and charts for optimization of thehood. Primary practice shows that the hood designed the way stated consumes 30per cent less power for air moving.
