Definition von gravitational convection im Englisch Englisch wörterbuch
The convection (carriage) of contents of a fluid, such as mass or heat, by means of currents induced in the fluid by bouyancy forces which are dependent on gravity acting upon density differences within the fluid. These density differences may result from various sources
Buoyancy-driven convection caused by density changes induced by mechanisms other than heat, are also types of gravitational convection.
