Jovian Clouds

Change the spinning speed of this sudsy, liquid-filled, sculpture to observe the smooth, laminar flow devolve into turbulence.

As visitors spin this exhibit the suds follow the flow patterns caused by the changing speed of the rotation. Depending on the acceleration of the orb, laminar regions, where everything is parallel, appear and no mixing occurs. As the spin slows or changes, the fluid mixes and the bands break up into turbulent swirls, ripples, and waves. Turbulent flow is complex and chaotic and converts organized, laminar flow into smaller and smaller forms.
