Flux in mass transfer
WebThe first term on the right-hand side represents the diffusive mass flux; the second term expresses the convective mass transfer, which results from the permeation of the bulk flow. This convective flow does not involve any convective bulk flow due to the pressure difference on the two sides of a porous membrane. Webby random thermal motion. Mass transfer is any process in which diffusion plays a role. The molar flux is just the molar flow rate, FA, divided by the cross sectional area, AC, normal …
