Linear dynamics of acoustic waves in a uniform shear flow is studied. It is shown that in the case of very low shear rate the dynamics of perturbations is adiabatic and can be fully described by the Liouville-Green asymptotic solutions. In contrast, in the flow with a moderate and high shear rate the dynamics of perturbations consists of additional phenomenon, acoustic wave overreflection. Asymptotic analysis is performed and analytical expressions for the transmission and reflection coefficients are derived and analyzed. [ABSTRACT FROM AUTHOR] |
