## On the Receptivity of Pipe Poiseuille Flow With a Bump on the Wall Under the Periodical Pressure

• 摘要: 采用渐近分析方法,建立了在周期压力驱动下,完全发展的圆管Poiseuille流当管壁存在局部不规则几何形状时的感受性问题模型．通过特征函数的双正交系统，应用Chebyshev配点法进行数值求解．通过算例计算，获得周期压力和矩形突起激发起的流体系统中的各种空间发展模态以及相应的感受性系数．从计算和分析可以知道，在流场的不同发展阶段不同的模态起着主导作用，这与在试验中观察到的扰动流场在不同位置的特性是一致的．
