Boundarylayer effects on the reflection of sound waves and weak shock waves at shallow incidence
Abstract
When either a plane acoustic wave or a weak shock wave is incident upon an infinite wall, the boundarylayer correction to the reflected wave becomes large if the angle between the wave front and the normal to the wall approaches zero. It is shown that transformation to moving coordinates leads to transonic flow problems whose solution permits removal of the singular behavior in each of these cases.
