    Flow-induced pulsations are frequently observed in pipe networks, when the main ow passes along a number of closed branches. Although there have been detailed studies on the pulsations generated by the separating ow along a closed side branch, the configurations with the ow entering or leaving the side branch have not been extensively analyzed. In this study, strong ow-induced pulsations have been measured in configurations with a mean ow diverging into a side branch and entering the main pipe from a side branch. Pulsations amplitudes almost as strong as observed in con??gurations with closed side branches have been measured.
