| 本文采用在线性火源的上方加一集烟罩的方法，通过测量排烟管道出口处速度分布来确定二维线性烟气羽流的质量流率，实验分自然排烟和机械排烟两种情况进行。实验结果与理论分析得到的计算结果进行了对比，结果表明，在工程设计允许的范围内，二维线性烟气羽流的质量流率用公式计算较为合理，其中常数Ｃ＿ｍ的取值为０．４８～０．５１。 |
| 英文摘要: |
| he mass flux of line thermal pumes was mearsured by fixing ahood apparatusabove line fires and measuring velocity distribution at the duct exit. The experimentswere carried out with the fan and without the fan respectively. Experimental resultswere compared with calculation results based on theoretical analysis. It was found thatthe mass flux of the line thermal plumes can be calculated approximately by using the e-quation z here C_m=0.48～0.51; 更多还原 |
