尾流前沿
英文
wake front-
We found the " forward stimulated raman scattering " will be excited if the pulse length is greater than plasma wave length. the " forward stimulation raman scattering " decreases the phase velocity and the amplitude of the wake wave which will lead to the reduction of maximum kinetic energy of the electrons trapped
結論是:當脈沖長度接近等離子體波長時,稀薄等離子體將發生「前向受激raman散射」 ,它使脈沖后沿拉長,導致尾流場的相速度變小,以至於被尾流場「捕獲」的電子最大動能大大下降。On the rotor blade pressure surface, the dominant frequencies of unsteady surface pressure are the up - stream blade wake passing frequency and its harmonics, and the amplitudes of pressure fluctuations decrease from leading edge to trailing edge
轉子葉片吸力面非定常壓力受葉片附面層和上游葉片尾跡共同影響,其主導頻率為上游葉片尾跡頻率及其倍頻,但是在吸力面前部氣流加速區壓力波動幅度沿流向增大,而在吸力面後部氣流減速區壓力波動幅度沿流向減小。
