Numerical investigation of three - dimensional separation flow in the rotor cascade of a steam turbine governing stage at large negative incidence
汽輪機(jī)調(diào)節(jié)級(jí)動(dòng)葉柵大負(fù)沖角工況下的三維分離流動(dòng)研究
Results from this investigation show that the loss generation within the coolant holes is substantial and that ejection into regions of low static pressure increases the loss per unit coolant mass flow . the results also reveal strong interactions between endwall coolant ejection and secondary flow in the blade passage . the secondary flow has a strong influence on coolant trajectories and coolant ejection delays the three - dimensional separation of the inlet boundary layer on the endwall , chang the secondary flow and reduces its associated losses
本文的研究成果顯示，冷卻孔內(nèi)產(chǎn)生的損失是主要的，并且低靜壓區(qū)域的冷空氣噴射會(huì)增加單位冷空氣質(zhì)量流的消耗；噴射的冷空氣與葉柵端壁流場之間有強(qiáng)烈的相互作用；二次流對(duì)冷卻空氣的流動(dòng)軌跡有較強(qiáng)的影響；冷空氣噴射能延緩端壁入口邊界層的三維分離、改變二次流從而減少其相關(guān)損耗。
