总压恢复系数 meaning in Chinese
stagnation pressure recovery factor
Examples
- 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
当进气道扩压段有侧向支柱存在时，进气道总压恢复系数和动能系数均有所降低，而流场畸变指数则显著增大。 - 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
摘要对一种蛇形进气道开展了地面工作状态下的抽吸试验研究，结果表明，在该状态下进气道出口截面的总压恢复系数较低、流场畸变较大。 - 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 %
本研究的蛇形进气道在出口马赫数为0 . 45时，总压恢复系数为0 . 90 ，综合畸变指数为13 . 85 % ，总压恢复较低，畸变较大，超出了一般航空发动机的承受范围。 - The relevance functions between total pressure recover coefficient and the parameters ( mach number , angle of attack , flow coefficient , angle of sideslip ) for subsonic submerged inlet in turbojet and turbofan engine were investigated
