解釋
失舉余量-
Exploring mechanism of stall margin enhancement of subsonic axial - flow compressor through steady micro tip injection
定常微量噴氣提高軸流壓氣機穩定工作裕度機理探討 -
Simulation results show that the surge line moved up - left relative to the original one and surge margin became larger when wet compression is used, which means wet compression can extend steady - operation regions of compressors and the si a - 02 gas turbine. at last, based on the moore - greitzer model surge and rotating stall of a compression system with wet compression is modeled with consideration of inlet evaporative cooling and compressor pressure rise when wet compression is used
哈爾濱工程大學博士學位論文最後,本文在壓縮系統moors grei上zer模型的基礎上,考慮進口蒸發冷卻的作用和壓氣機濕壓縮過程的作用,推導出了濕壓縮系統喘振和旋轉失速的統一模型,該模型可以模擬系統發生喘振和旋轉失速時的瞬態響應以及噴水濕壓縮對系統瞬態響應的影響。 -
Analysis of the effect on tip flow topologies led to some preliminary conclusions as to the flow physics involved in the stall margin improvements afforded by tip injection
