چکیده

Dynamic analysis of supported pipes conveying pulsating fluid is investigated in Hamiltonian system using precise integration method PIM . First, symplectic canonical equations of supported pipes are deduced with state variable vectors composed of displacement and momentum. Then, PIM with linear interpolation formula is proposed to solve these equations. Finally, this approach’s precision is testified by several numerical examples of pinned-pinned pipes with different fluid velocities and frequencies. The results show that PIM is an efficient and rapid approach for flowinduced dynamic analysis o f supported pipes.

Analysis of the nonlinear axial vibrations of a cantilevered pipe conveying pulsating two-phase flow

The parametric resonance of the axial vibrations of a cantilever pipe conveying harmonically perturbed two-phase flow is investigated using the method of multiple scale perturbation. The nonlinear coupled and uncoupled planar dynamics of the pipe are examined for a scenario when the axial vibration is parametrically excited by the pulsating frequencies of the two phases conveyed by the pipe.
