Abstract

Stability analysis of pipe conveying fluid with internal flow is studied in this paper. Finite Element Analysis is used to study the dynamic analysis of pipe conveying fluid stiffened by linear spring. Several effective parameters play an important role in stabilizes the system, such as stiffness addition. The effect of stiffness addition (linear spring) and effect of spring location was studied. Also, effect of flow velocity on the dynamic stability of the system was taken into the consideration. There is a spring constant at which the dynamic behavior becomes more sensitive and the spring offers best results for frequency of the system. Spring locations depend on the flow velocity and spring constant itself.

Keywords: Stability, Finite element method; Pipe conveyed fluid; linear spring stiffness.
