Granite Kugel
rolling ball fountains have something to say to those who think a ball fountain cannot be elegant. The marble ball which features at its best in this design is glossier than a stone ball and can be purchased at any water feature supplies store. The kugel ball that is the basis of this ball rolling type of fountain, adds that extra attention to detail when installed in backyard water fountains. As a garden ornament this type of fountain offers a variety into many garden fountain ideas, where you don’t have to just stop with stone spheres, but also explore the great, big world of rolling ball fountains.
Sphere fountain
spinning sphere fountain is a twist off of the sphere fountain that makes use of stone spheres that put on a trapeze act by balancing in place indoors. As a fountain garden design, the garden ball and the garden spheres are close substitutes to the sphere fountain ball. They work well together as interior water features, with its clean swept lines and balanced blend of modernity with ancestral raggedness. With a natural rock base, these water features create quite the sensation, especially since its fountains are a mix of sphere water fountain and kugel ball mashed together to create a spin on a new classic.
A kugel fountain (also called a "floating" sphere fountain or by the pleonasmic name kugel ball) is a water feature or sculpture where a sphere sits in a fitted hollow in a pedestal, and is supported by aquaplaning on a thin film of water. Pressurized water flows between the sphere and socket, creating a mechanical hydrostatic bearing that is nearly frictionless. The sphere can weigh thousands of kilograms, but the efficient bearing allows it to be spun by the force of a hand. The sphere does not float, being denser than water; it is often made from granite. The hydraulics of the fountain can be controlled so that the axis of rotation of the sphere changes continually. Ring sculptures that rotate on an axis are also built. Kugel fountains can be found all over the world. Many are at popular tourist destinations, such as science museums, shopping centers, lobbies, and gardens.
The Kugel fountain, where a sphere sits in a fitted socket fed by a thin film of pressurized water flowing between the sphere and the socket, was treated as a bearing without referring to any mathematical or practical evidence that can support this idea. Hence, in this study the hydrodynamics of this sculpture will be handled to support the idea of treating the fountain as a bearing and to prove that it is a hydrostatic thrust spherical bearing.
he massive granite sphere known as the Grand Kugel (the largest construction of its kind in the world) can be spun or stopped with almost no effort thanks to a neat effect of science.
A kugel ball is comprised of a perfectly spherical stone ball that is set into a matching, perfectly concave cup. Water is then forced in from the bottom of the cup creating an evenly distributed, incredibly thin layer of water. The ball, no matter how heavy, can then be moved on the liquid surface as though it weighed nothing at all.
