In the field of physics, engineering, and earth sciences, advection is the transport of a substance or quantity by bulk motion of a fluid. The properties of that substance are carried with it. Generally the majority of the advected substance is also a fluid.

Mar 31, 2020 · In short, advection is specifically dependent on the currents within a fluid, while convection is a broader process that also contains diffusive heat transfer. As such, advection can only exist in gases and liquids, and it isn't possible in a solid.

The meaning of ADVECTION is the usually horizontal movement of a mass of fluid (such as air or an ocean current); also : transport (as of pollutants or plankton) by such movement.

ADVECTION definition: 1. the transport of a substance or of heat by the flow of a liquid: 2. the transport of a…. Learn more.

In fluid dynamics, advection is a type of convection, with the other type of convection being diffusion. Both advection and diffusion act to move around various intensive properties of a fluid. In advection, properties are transported by bulk motion of the fluid.

May 16, 2023 · Advection is the process by which contaminants are transported by the flowing fluid or solvent in response to a hydraulic gradient. Due to advection, nonreactive solutes are transported at an average rate equal to the seepage velocity of the fluid.
