主 题：Double shell Annular flow Coupled system Dispersion equation
摘 要：The dispersion behaviour of a double shell-fluid system, which consists of two thin concentric cylindrical elastic shells coupled by the entrained annular fluid, is a fundamental for investigation of its vibroacoustical characteristics. Based on Flugge s infinite shell equations,the sound wave equation for the fluid field and boundary conditions at the fluidstructure interfaces, the dispersion equationfor the system is deduced and a corresponding numerical example is given in the paper.
