Abstract
The present paper investigates the propagation of time harmonic waves in a two layered hollow poroelastic cylinder in contact with inviscid fluids. The hollow poroelastic two layered cylinder is assumed to be infinite in axial direction. The outer and inner surfaces of the two layered cylinder are in contact with fluids and at the interface stresses and displacements are continuous. The frequency equation for wave propagation for a pervious is obtained. Non-dimensional phase velocity is computed as a function of wave number and presented graphically for two types of two layered cylinder for arbitrary parameters of the fluid in contact. Numerical results show that, in general, phase velocity is more in absence of outer fluid compared to the case of absence of inner fluid. Several other particular cases are discussed.
