在马赫数为5的压缩斜板干扰中，在来流未扰动湍流边界层和非定常分离激波下同时测量了脉动壁压。有条件的采样算法，可变窗口集成平均技术，和可变间隔时间平均技术已被用来调查的可能性之间的相关性的压力波动在来流和分离激波运动。
Fluctuating wall pressures have been measured simultaneously in the incoming undisturbed turbulent boundary layer and under the unsteady separation shock in a Mach 5 compression ramp interaction. Conditional sampling algorithms, a variable-window ensemble averaging technique, and the variable interval time averaging technique have been used to investigate the possibility of a correlation between pressure fluctuations in the incoming flow and the separation shock wave motion.
