When there are struts at the divergent parts of inlet, the total pressure recovery coefficients and the kinetic energy coefficients of inlet decrease, and the flow distortion index increases obviously
當進氣道擴壓段有側向支柱存在時，進氣道總壓恢復系數和動能系數均有所降低，而流場畸變指數則顯著增大。 -
The results prove that : ( 1 ) when the mach number of the flow at the exit increases, the total pressure recovery decreases, and the circular steady total pressure distortion coefficient, turbulence intensity and synthesis distortion increase
研究結果表明： （ 1 ）地面工作狀態下，隨著出口馬赫數的增加，蛇形進氣道出口截面的總壓恢復系數不斷下降，而穩態周向畸變指數、紊流度和綜合畸變指數均上升，穩態徑向畸變指數變化不大。 -
Abstract : optimum distances between primary nozzle exit and mixing tube inlet, static pressure recovery of the mixing flow in mixing tube 、 total pressure distributions at the exit of mixing tube 、 pumping coefficients and total pressure losses of the exhaust ejector systems with four different types of primary nozzles have been measured in the experiments
文摘:對4種主噴管組成的排氣引射系統的引射系數和總壓損失、各主噴管出口與混合管進口之間的最佳間距、混合氣流在混合管內的靜壓恢復及混合氣流在混合管出口處的總壓分佈等進行了測量和對比。 -
When the serpentine inlet is running at the exit mach number ma ( subscript e ) = 0. 45, the total pressure recovery coefficient equals 0. 90, and synthesis distortion equals 13. 85 %
本研究的蛇形進氣道在出口馬赫數為0 . 45時，總壓恢復系數為0 . 90 ，綜合畸變指數為13 . 85 % ，總壓恢復較低，畸變較大，超出了一般航空發動機的承受范圍。 -
Secondly, the cfd method is used to study the flowfields in the laser chamber and the loss of the total pressure in several types of nozzles. the answer shows that reducing the length of the nozzles and the high of the throats in the nozzles can reducing the loss of the total pressure. and the answer also shows that the small nozzles with helium injected in the base region are good for laser chamber pressure recovery
其次，本文利用cfd技術模擬了光腔流場，研究了幾種噴管的總壓損失特性。研究結果表明，對于平面對稱噴管，減小噴管長度，增加喉道高度有利於減少總壓的損失。用cfd技術對光腔段的模擬表明，採用小尺寸噴管，並且在基區大量注入氦氣有利於激光器壓力恢復。 -
Experimental results of the air pumping of a serpentine inlet under ground running show that the total pressure recovery at the exit is low and the distortion at the exit is large
