This paper addresses the multimodal acoustic wave propagation in elastic pipes which can carry multiphase fluids. The waveguide characteristics of circular, fluid filled pipes and the influence of elasticity of the outer boundaries (pipe wall) in relation to the compressibility of the filling liquid and the inner boundaries due to an additional fluid phase are discussed – in comparison to the assumption of rigid walls. The presented studies base on simulations which combine the fluid pressure acoustics and the solid structure mechanics of a circular pipe which is filled with up to two fluid phases.
