    Title: Propagation of real fluid in tubes. Flow induced vibrations models of Chen a Paidoussis  Author: Yoshinov, R. Date: 1994 Abstract: Investigation of flow induced vibrations caused by fluid propagation in tubes dates from 1958. This relies on the fact that lateral amplitudes of deflection caused by this propagation are small (1/1000 - 1/10 sm.). They should be ignored if there were not many cases in practice where even these small amplitudes of oscillation are dangerous. ... Library:
