畸变指数 meaning in English
distortion index
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。 - 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 collection of illustrative plates of air interface plane ( aip ) , steady index , unsteady index , synthesized index and the loss of the stability margin are given out , and get some valuable results are summarized by analyzing the data
试验中处理各插板下的压气机气动界面aip界面的总压图谱,稳态畸变指数,动态畸变指数,综合畸变指数,稳定性损失裕度等等一些参数,分析之后获得一些有益的结果。 - 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
研究结果表明： ( 1 )地面工作状态下，随着出口马赫数的增加，蛇形进气道出口截面的总压恢复系数不断下降，而稳态周向畸变指数、紊流度和综合畸变指数均上升，稳态径向畸变指数变化不大。 - The results of the experiment show that the synthesized index , unsteady index and steady index inflect the stability margin of the compressor well . and show that the insert - board experiment can get the enough weight in the synthesized index . and also show that the low - press - area of the steady total - press moves along the rotor circumvolving direction
试验结果表明,综合畸变指数,动态畸变指数,稳态畸变指数对压气机稳定性有很大作用;同时试验还表明,插板能够产生较大的动态畸变指数分量;稳态压力图谱低压区随着转子转动方向转动;以及其他一些有益的结果。
