軸流壓氣機小擾動誘發旋轉失速的試驗研究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。So under some situations, for example at the point of inception of surge or rotating stall, wet compression can be used to vanish surge and rotating stall, which will extend compressor steady operation region
在一定的條件下，如在系統剛發生喘振或旋轉失速的時候，噴水濕壓縮可以用來消除喘振或旋轉失速，這有利於增大壓氣機的穩定運行范圍。And cpld / fpga can make sure of the reliable and fast character of the control. the turbine is large machine working under the high temperature and high press. so opc must be reliable
鑒于汽輪機是高溫、高壓、高速旋轉的大型動力設備，對其轉速控制必循做到萬無一失，故而對控制裝置的可靠性要求很高。As the air speed came on, the plane slowly, slowly rolled out with heavy, serious vibration problems because that prop was still spinning with parts of it missing, obviously out of balance
隨著飛行速度起來，飛機慢慢地、慢慢地翻轉過來，但是顫抖劇烈，顯然是因為那個已經失去一些部件的螺旋槳仍在旋轉，失去了平衡。The spin, sometimes called the negative spin, occurs when the angle of attack of the canopy is increased and one side is stalled causing it to drop almost vertically and spin on its yaw axis
旋轉，有時候叫反向旋轉，發生於當傘的攻角增加，而且單側失速時，引起幾乎垂直地下墜，同時繞著它的偏移軸心旋轉。In t his p aper r otating s tall a nd t he inlet v ortex in c entrifugal fans with inlet v ane control has been studied in laboratory. the harmonic wavelet is firstly used for time - frequency analysis and feature extraction of pulsation amplitude and frequency and development of rotating stall and inlet vortex. the development rule of rotating stall and inlet vortex and the effect to fans performance from the two has been found
文中對採用入口導流器調節的離心通風機的旋轉失速和進口渦流問題進行了實驗研究，並藉助諧波小波對旋轉失速和進口渦流的頻率、幅值特性及動態過程進行了時頻分析和特徵提取，揭示了旋轉失速和進口渦流發展的規律及二者對風機性能的影響。The high speed revolves machine design with an important problem that circulate the inside is a control with lower the shafting force the vibration responds to, still exsist at the same time another an also important problem : the rotor loses steady with from arouse the vibration
高速旋轉機械設計和運行中的一個重要問題是控制和降低軸系的強迫振動響應，同時還存在另一類同樣重要的問題：轉子動力失穩和自激振動。Speed, for itself, is a pale wall. it rotates endless. after all, we fell losing something in a trance
速度本身就是一道蒼白的墻面。無盡地旋轉，終將在恍惚中悵然所失。Experimental study shows : it was able to distinguish between rotating stall and the inlet vortex.,
實驗表明，旋轉失速和進口渦流能夠區分，且區域界限分離明顯。Abstract : concerning the models for discribing aerodynamic stability of axial flow compressor, the original model is one - dimensional, and it is reasonable for the onset of surge only. for the onset of rotating stall, there are just some two - dimensional models at published literatures. a three - dimensional aerodynamic of compressor has been presented in this paper. an aerodynamic stability model concerning radial disturbance of compressor is presented. the calculated results show that the occurrence of radial disturbance is related to the axial velocity disturbance, which has important effect on aerodynamic stability of compressor. the position of onset of stall, in blade tip or hub, is dependent upon the characteristics of blade element. the comparisons of calculated results predicted by 2d and 3d aerodynamic stability model have also been made in this paper
