water-well rig
解釋
水井鉆機-
Experimental studies on s1a - 02 gas turbine with water injection into compressor interstage / inlet as well as that on turbocharger self - loop test rig with inlet water injection are introduced. test results are in good accordance with simulation results, wet compression can lower compression work and increase engine power output so engine performance is enhanced, if engine power output is not changed, efficiencies of compressor and this engine become higher and turbine inlet temperature and fuel consumption become lower and if keeping t4 the same as that before wet compression is used, efficiencies become furthermore higher and engine power output increases greatly
實驗結果和計算結果同樣表明：濕壓縮減少了壓氣機所消耗的壓縮功，增加了燃氣輪機的輸出功率，提高了燃氣輪機性能，如果保持發動機輸出功率恆定，濕壓縮可以提高壓氣機和整個燃氣輪機機組的效率，與此同時，渦輪進口溫度t _ 3 ~ *和燃油消耗率下降；如果保持渦輪排氣溫度t _ 4 ~ *恆定，壓氣機和燃氣輪機機組效率進一步提高，燃氣輪機輸出功率增加。 -
