A Heron's fountain operates on the interaction between water and air. In FLOW-3D HYDRO, you can utilize dynamic void pressure to simulate the effects of air pockets without having to model a more computationally expensive two-phase (air and water) simulation. In this video, water drains from the top reservoir to the bottom sealed reservoir. As air is displaced up into the middle reservoir, water is forced up the pipe and out into the top reservoir. The plunging fountain jet also spins a moving impeller as an object that is allowed to rotate about a fixed axis. Learn more at flow3d.com/hydro
