Direct numerical simulation of interaction of twin transitional fountains in a homogeneous fluid
Conference Publication ResearchOnline@JCUAbstract
In this paper, the transient behavior of the interaction of twin transitional round fountains in a homogeneous fluid with the Froude number and the Reynolds number in the range of 1<=Fr<=10 and 100<=Re<=1000 has been investigated using three-dimensional direct numerical simulation. The results show that the behavior of the interaction of twin transitional fountains can be categorized as either steady or unsteady. The steady category can be further divided into two subregimes: flapping and bobbing-flapping, whereas the unsteady interaction can be divided into four sub-regimes: flapping, bobbing-flapping, circling and transitional/turbulent, which are also mapped on to an Fr-Re plot.
