阀出口马赫数 - The results show that to design a supersonic / hypersonic nozzle of wind tunnel must consider the effect of variable specific heat , which gives reference to nozzle and wind tunnel design
考虑这一因素后，喷管出口马赫数接近设计马赫数，其设计精度有较大提高。本方法可为超音速高超声速喷管设计和反设计提供参考。 - 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 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。 - To prove the accuracy of the mach number , and the parameter homogeneity of the design nozzle " s exit , cfd calculate has carried on the design results . under the condition of supersonic and hypersonic flow , and a certain range of temperature , and mach number , the conclusion of the influence of specific heat to nozzle design is drawn
为了验证所设计的喷管出口马赫数的大小和喷管出口流场的均匀性，采用nnd格式和b l湍流模型求解雷诺平均n - s方程，对设计结果进行了cfd验算，得出了在一定温度范围内，超音速、高超声速流动的条件下，不同马赫数范围内变比热容对喷管型面和喷管出口马赫数的影响。
