| 1. | According to thermal state similitude model experiment of the langya mountain hydropower station , we adopt different velocity of air ventilation and exclude air proportion of upriver and downriver , this paper contrast the air distribution of the dynamo floor on each method , and educe the best projects of arch crest supply air that adapt to langya mountain hydropower station ’ s dynamo floor : g = 17 . 4 10 ~ 4m ~ 3 / h , 22 vents , d = 600mm , the scale of volume 1 : 3 , t0 = 16 . 9 . it ’ s also thought that improved any side of volume can reduce its temperature . when study on the air supply of langya mountain hydropower station ’ s underground dynamo floor by cfd software , it proved that cfd software is correct when compare with model experiment . when arrange the number of 5 kinds of vents , it concluded that the number of vents 14 to 22 , it can ’ t change velocity , in 36 to 40 can lead to reduction of velocity . when vent in 14 to 36 , the parameter kt doesn ’ t change , when the number is as large as 36 , kt reduces
在此基础上,模拟了5种风口布置方案和送风量的改变对发电机层温度场和速度场的影响,获得了些可供参考的结论:在风量和送风速度不变的条件下,风口个数在( 14 ~ 22 )小范围变化时,工作区平均风速基本不变,大幅度增加风口个数( 36 ~ 44 )就会导致工作区平均风速的降低,风口数在14 ~ 36之间对工作区的温度不均匀系数影响不大,当风口数> 36时,温度不均匀系数随着风口数的增多而变小,速度不均匀系数一直随着风口数的增加而减少;在风口布置和尺寸不变的情况下,送风量变化时,工作区平均温度随送风量增大而降低,平均温度的降低量逐渐趋于减少,能量利用系数先是随着送风量的增加而增大,后随送风量增加而减少。 |
