Amplification of non-linear standing waves in a cylindrical cavity with varying cross section
Abstract
An experimental and theoretical investigation is presented of the possibility of amplifying nonlinear standing waves in a cylindrical cavity that is closed at one end, with oscillations driven by a jet that is directed towards the open end of the cavity. A simplified wave diagram is given which facilitates the determination of the amplification ratio at large amplitude. Agreement between experimental and theoretical values of the amplification ratio is found to be good, and a pressure amplitude as high as 28 bars has been recorded at the cavity end wall when the oscillations are driven by an air jet at Mach 2.
