Abstract

In this study the behavior of the interaction of twin fountains in a homogeneous fluid is studied experimentally using flow visualization and noninvasive PIV technique over the range of 25⩽Re⩽400 and 1⩽Fr⩽5. The results show that the behavior can be categorized into several regimes: flapping steady; bobbing/flapping/steady; flapping unsteady; bobbing/flapping unsteady; and unsteady circling, which are mapped onto a Re-Fr map.
