Based on the Floquet-Liapunov theory, this paper proposes an efficient one-dimensional search approach for stability analysis of pipes conveying pulsatile flow. The instability boundaries of a clamped-clamped pipe analyzed in this paper. The numerical results are satisfactory compared with existing results. Moreover, an instability region which failed to appear in ordinary numerical analyses is detected by our computations.
