SUMMARY:The Critical Layer in Quadratic-Shear Boundary Layers over Acousti
 c Linings - Matthew King (University of Warwick)

DESCRIPTION:When Modelling sound attenuation in jet engines an impedance b
 oundary condition is used to capture the effects of acoustic liners. To ke
 ep this boundary condition simple in form one can consider a sheared flow 
 profile with no slip at the boundary. Doing so however gives rise to a reg
 ular singularity of the Pridmore-Brown Equation known as the Critical Laye
 r. \n\nThis talk will give an outline of one way in which the critical lay
 er may be considered. We will then focus on the specific case of a mean fl
 ow profile of a uniform flow with a quadratic boundary layer. We will both
  be drawing comparisons to previous literature and examining behavior that
  had been previously hypothesised to not be able to occur. In particular w
 e will see that this behaviour is commonplace\, and results in previous un
 seen importance of the critical layer on the far-field.
