Abstract

The conditions are given for which the more flexible of two cantilevered, telescoping tubes conveying fluid can be self-excited by flow leaking from an un-constricted slip joint. Also, a physical explanation of the excitation mechanism is discussed, and a design rule to avoid the mechanism is presented. In addition, the results for the un-constricted slip joint are shown to be similar to those for slip joints having annulus constrictions at very short engagement lengths
