Abstract: Vibration damping of a plate by means of a fluid layer is investigated. First, the frequency-dependent flow resistance of a fluid layer is explained with a simple illustration of the damping ...

Abstract: In the commonly used definition of acoustic “radiation efficiency” of a plate, it is assumed that the amplitude of a traveling harmonic wave on the plate is kept constant, independent of the ...

Abstract: The effect of refraction by a flow boundary layer on the radiation of sound from a bending wave on a plate is investigated. Based on the relative velocities of the bending wave and the ...
