  3. 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

    在此基礎上，模擬了5種風口布置方案和送風量的改變對發電機層溫度場和速度場的影響，獲得了些可供參考的結論:在風量和送風速度不變的條件下，風口個數在（ 14 ~ 22 ）小范圍變化時，工作區平均風速基本不變，大幅度增加風口個數（ 36 ~ 44 ）就會導致工作區平均風速的降低，風口數在14 ~ 36之間對工作區的溫度不均勻系數影響不大，當風口數> 36時，溫度不均勻系數隨著風口數的增多而變小，速度不均勻系數一直隨著風口數的增加而減少;在風口布置和尺寸不變的情況下，送風量變化時，工作區平均溫度隨送風量增大而降低，平均溫度的降低量逐漸趨于減少，能量利用系數先是隨著送風量的增加而增大，后隨送風量增加而減少。
