Abstract

The analytical model of a fluid filled cylindrical shell is used to analyse the wave propagation in the quarter wavelength absorbers. It has been found, that due to the strong fluid-structure interaction, the considerable wave speed reduction can be reached using a compliant shell. Thus via parametric studies, the dimensions of the absorbers are assessed to reach more efficient and compact design. Furthermore, the use of the compliant materials allows treating the fluid to be incompressible, which helps to simplify the calculations.
