Kugel ball nature: hydrodynamics-mathematics-design

Applications in Engineering Science, 2022
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.
