A rotating tank is a device used for
fluid dynamics
In physics, physical chemistry and engineering, fluid dynamics is a subdiscipline of fluid mechanics that describes the flow of fluids – liquids and gases. It has several subdisciplines, including (the study of air and other gases in motion ...
experiments. Typically cylinders filled with water on a rotating platform, the tanks can be used in various ways to simulate the
atmosphere
An atmosphere () is a layer of gases that envelop an astronomical object, held in place by the gravity of the object. A planet retains an atmosphere when the gravity is great and the temperature of the atmosphere is low. A stellar atmosph ...
or
ocean
The ocean is the body of salt water that covers approximately 70.8% of Earth. The ocean is conventionally divided into large bodies of water, which are also referred to as ''oceans'' (the Pacific, Atlantic, Indian Ocean, Indian, Southern Ocean ...
.
For example, a rotating tank with an ice bucket in the center can represent the Earth, with a cold pole simulated by the ice bucket. Just as in the atmosphere,
eddies and a westerly
jetstream form in the water.
