文摘

The so-called “FSI four-equation model” describes the axial vibration of liquid-filled pipes. Two equations for the liquid are coupled to two equations for the pipe, through terms proportional to the Poisson contraction ratio, and through mutual boundary conditions. In 1955 and 1956, Skalak defined this basic model, which disregards friction and damping effects.
