Advection
Q. Advection is- Published on 03 May 16a. Fluid's bulk motion
b. Transporting a substance by a fluid due to the fluid's bulk motion
c. Movement of fluid’s molecules
d. Movement of fluid from lower pressure place to higher pressure place
ANSWER: Transporting a substance by a fluid due to the fluid's bulk motion
- Advection is a transport mechanism of a substance or conserved property by a fluid due to the fluid's bulk motion.
- An example of advection is the transport of pollutants or silt in a river by bulk water flow downstream. Another commonly advected quantity is energy or enthalpy.
- Advection is sometimes confused with the more encompassing process of convection.
- Convection is the concerted, collective movement of groups or aggregates of molecules within fluids (e.g., liquids, gases) and rheids, through advection or through diffusion or as a combination of both of them.
