What is convective mass transfer?

Mass transfer by convection involves the transport of material between a boundary surface (such as solid or liquid surface) and a moving fluid or between two relatively immiscible, moving fluids.
In forced convection type the fluid moves under the influence of an external force (pressure difference)as in the case of transfer of liquids by pumps and gases by compressors.
Natural convection currents develop if there is any variation in density within the fluid phase. The density variation may be due to temperature differences or to relatively large concentration differences.
