The work is devoted to investigation of the dynamic behavior of elastic coaxial cylindrical shells interacting with an ideal compressible fluid. The shell behavior is examined in the framework of the classical shell theory, using the variational principle of virtual displacements as a mathematical formulation. The fluid is described in terms of potential theory. With this approach, the stated problem reduces to simultaneous solving of four sets of equations using the finite element method. For shells with different boundary conditions the numerical investigations have been carried out to explore the effects of the annular gap on the boundary of hydroelastic stability.
Keywords: coaxial shells, potential fluid, finite element method, stability, flutter.
